Nonlinear Biomechanical Characteristics of Deep Deformation of...Mon Sep 23 2019

Published new post (Nonlinear Biomechanical Characteristics of Deep Deformation of Native RBC Membranes in Normal State and under Modifier Action) on NANOSENSORS Blog The mechanical properties and structural organization of membranes determine the functional state of red blood cells (RBCs). Deformability is one of the key physiological and biophysical indicators of RBC. Changes of the mechanical characteristics of cell membranes can lead to a decrease in the rate of capillary blood flow and to development of stagnant phenomena in the microcirculation, and it can also reduce the amount of oxygen delivered to the tissues.* In the article “Nonlinear Biomechanical Characteristics of Deep Deformation of Native RBC Membranes in Normal State and under Modifier Action” Elena Kozlova, Aleksandr Chernysh, Ekaterina Manchenko, Viktoria Sergunova and Viktor Moroz describe how they evaluated the ability of membranes of native human red blood cells (RBCs) to bend into the cell to a depth comparable in size with physiological deformations using the methods of atomic force microscopy ( AFM ) and atomic force spectroscopy ( AFS ).* As a true estimation of the elastic properties of RBC membranes can be obtained only by measurement of native cell properties the aim of the experiments was to study nonlinear mechanical characteristics of deep deformation of native RBC membranes in normal state and under the action of modifiers, in vitro to make sure that the result would be the closest to the characteristics of a living biological object.* NANOSENSORS™ rounded AFM tips of the type SD-R150-T3L450B with a typical tip radius of 150 nm from the NANOSENSORS Special Developments List were used to measure the deformation of the RBC membrane by atomic force spectroscopy ( AFS ).* https://www.nanosensors.com/pdf/SpecialDevelopmentsList.pdf Please have a look at the NANOSENSORS blog for the full citation and a direct link to the full article. #ForceSpectroscopy #CellBiology #erythrocytes #AFMprobes

Published new post (Direct evidence for grain boundary passivation in Cu(In,Ga)Se2 solar cells through alkali-fluoride post-deposition treatments) on NANOSENSORS Blog The properties and performance of polycrystalline materials depend critically on the properties of their grain boundaries.* In the article “Direct evidence for grain boundary passivation in Cu(In,Ga)Se2 solar cells through alkali-fluoride post-deposition treatments “ Nicoleta Nicoara, Roby Manaligod, Philip Jackson, Dimitrios Hariskos, Wolfram Witte, Giovanna Sozzi, Roberto Menozzi and Sascha Sadewasser investigate the direct evidence for grain boundary passivation in Cu(in,GA)Se2 solar cells through alkali-fluoride treatment. They present a KPFM study on the electronic GB properties in CIGSe deposited by co-evaporation and compare the effect of KF-, RbF-, and CsF-PDT.* Their results suggest that heavier alkali elements might lead to better passivation by reducing the density of charged defects and increasing the formation of secondary phases at grain boundaries.* The KPFM measurements for the study were carried out with platinum iridium coated NANOSENSORS™ PointProbe® Plus PPP-NCLPt AFM probes.* https://www.nanosensors.com/pointprobe-plus-non-contact-tapping-mode-long-cantilever-ptir5-coating-afm-tip-PPP-NCLPt Please have a look at the NANOSENSORS blog for the full citation and a direct link to the full article. #ElectronicProperties #KelvinProbeForceMicroscopy #PolycrystallineMaterials

Inhalation of fibrous erionite particles has been linked to malignant mesothelioma. Accordingly, erionite is considered the most carcinogenic mineral. The reactivity and the nature of erionite biotoxicity has been the subject of intensive research. Despite very close chemical and structural relationships between erionite and offretite, the reactivity of offretite in lung fluids remains unknown.* In their paper “Real-Time Observation of Fibrous Zeolites Reactivity in Contact with Simulated Lung Fluids (SLFs) Obtained by Atomic Force Microscope (AFM)”, Matteo Giordani, Georgia Cametti, Fulvio Di Lorenzo and Sergey V. Churakov investigate the interaction of erionite and offretite surfaces with simulated lung fluids by means of in situ atomic force microscope (AFM).* The outcomes presented in the paper mentioned above represent an important step in understanding the complex processes occurring at the surfaces of mineral fibres that could be involved in the toxicological pathway.* The topography scans were performed in tapping mode with a NanoWorld Arrow-UHFAuD https://www.nanoworld.com/ultra-high-frequency-afm-tip-arrow-uhf-aud AFM probes under different experimental conditions. To better discriminate the role of the tip from the actual fluid-surface interaction, additional measurements were performed in air and in water in contact mode using an Al-coated NanoWorld Arrow-CONTR https://www.nanoworld.com/contact-mode-reflex-coated-afm-tip-arrow-contr AFM cantilever.

A tension-adhesion feedback loop in plant epidermis – NANOSENSORS BlogSun Sep 01 2019

Published new post (A tension-adhesion feedback loop in plant epidermis) on NANOSENSORS Blog Mechanical forces have emerged as coordinating signals for most cell functions. Yet, because forces are invisible, mapping tensile stress patterns in tissues remains a major challenge in all kingdoms.* In their research paper “A tension-adhesion feedback loop in plant epidermis” Stéphane Verger, Yuchen Long, Arezki Boudaoud and Olivier Hamant take advantage of the adhesion defects in the Arabidopsis mutant quasimodo1 (qua1) to deduce stress patterns in tissues.* Using suboptimal water potential conditions, the authors revealed the relative contributions of shape- and growth-derived stress in prescribing maximal tension directions in aerial tissues. Consistently, the tension patterns deduced from the gaping patterns in qua1 matched the pattern of cortical microtubules, which are thought to align with maximal tension, in wild-type organs. Conversely, loss of epidermis continuity in the qua1mutant hampered supracellular microtubule alignments, revealing that coordination through tensile stress requires cell-cell adhesion.* Based on the results achieved with plants presented in this research paper, the analysis of basement membrane continuity, and its disruption, may very well help understand how consistent supracellular epidermal patterns relate to mechanical stress, in parallel to the well-established role of cadherin and stress in cell-cell adhesion and epidermal functions.* NANOSENSORS™ special development Sphere AFM probes ( SD-Sphere-NCH-S ) with 400 nm tip radius and 42 N/m spring constant were used. https://www.nanosensors.com/pdf/SpecialDevelopmentsList.pdf Please have a look at the NANOSENSORS blog for the full citation and a direct link to the ful article. https://www.nanosensors.com/pdf/SpecialDevelopmentsList.pdf Please have a look at the NANOSENOSRS blog for the full citation and a direct link to the full article. #CellStiffness #microtubules #AtomicForceMicroscopy #nanoindentation

New post - Launching of hyperbolic phonon-polaritons in h-BN slabs by resonant metal plasmonic antennas (https://www.nanoworld.com/blog/launching-of-hyperbolic-phonon-polaritons-in-h-bn-slabs-by-resonant-metal-plasmonic-antennas/?utm_source=Facebook&utm_medium=Blog&utm_content=Launching+of+hyperbolic+phonon-polaritons+in+h-BN+slabs+by+resonant+metal+plasmonic+antennas&utm_campaign=NanoWorld+Blog) has been published on NanoWorld Blog. Launching and manipulation of polaritons in van der Waals materials offers novel opportunities for applications such as field-enhanced molecular spectroscopy and photodetection.* Particularly, the highly confined hyperbolic phonon polaritons (HPhPs) in h-BN slabs attract growing interest for their capability of guiding light at the nanoscale. An efficient coupling between free space photons and HPhPs is, however, hampered by their large momentum mismatch.* In the article “Launching of hyperbolic phonon-polaritons in h-BN slabs by resonant metal plasmonic antennas” P. Pons-Valencia, F. J. Alfaro-Mozaz, M. M. Wiecha, V. Biolek, I. Dolado, S. Vélez,P. Li, P. Alonso-González, F. Casanova, L. E. Hueso, L. Martín-Moreno, R. Hillenbrand and A. Y. Nikitin show that resonant metallic antennas can efficiently launch HPhPs in thin h-BN slabs. Despite the strong hybridization of HPhPs in the h-BN slab and Fabry-Pérot plasmonic resonances in the metal antenna, the efficiency of launching propagating HPhPs in h-BN by resonant antennas exceeds significantly that of the non-resonant ones. Their results provide fundamental insights into the launching of HPhPs in thin polar slabs by resonant plasmonic antennas, which will be crucial for phonon-polariton based nanophotonic devices.* A commercial s-SNOM setup in which the oscillating (at a frequency Ω≅270kHz) metal-coated (Pt/Ir) AFM tip (NanoWorld ARROW-NCPt) was illuminated by p-polarized mid-IR radiation, was used.* https://www.nanoworld.com/tapping-mode-platinum-coated-afm-tip-arrow-ncpt Please have a look the NanoWorld blog for the full citation and a direct link to the full paper.

Published new post (Conductive-probe atomic force microscopy and Kelvin-probe force microscopy characterization of OH-terminated diamond (111) surfaces with step-terrace structures) on NANOSENSORS Blog Diamond has a high breakdown field, high carrier mobilities and the highest thermal conductivity. That is why diamond is a promising material for next generation high-power devices such as field effect transistors.* In their paper “Conductive-probe atomic force microscopy and Kelvin-probe force microscopy characterization of OH-terminated diamond (111) surfaces with step-terrace structures”, Masatsugu Nagai, Ryo Yoshida, Tatsuki Yamada, Taira Tabakoya, Christoph E. Nebel, Satoshi Yamasaki, Toshiharu Makino, Tsubasa Matsumoto, Takao Inokuma and Norio Tokuda report about a detailed characterization of OH-terminated diamond (111) surfaces with step-terrace (ST) and bunching-step (BS) regions. In order to obtain the OH-terminated diamond (111) surfaces, they combined three techniques: anisotropic diamond etching by thermochemical reaction between Ni and diamond in high-temperature water vapor, hydrogen plasma treatment24) and water vapor annealing. For characterization of the topography as well as electronic surface properties, atomic force microscopy (AFM), Kelvin-probe force microscopy (KPFM) and conductive-prove AFM (CPAFM) were applied.* They found that the contact potential difference (CPD) and current were highly correlated with the surface topography and concluded that the interface states were generated around steps on the OH-terminated diamond (111) surfaces.* The results presented in this paper indicate that atomically flat diamond surfaces with minimal step densities are required to form ideal MOS structures with minimized interface state densities.* The CPD maps of the OH-terminated diamond (111) surfaces were obtained by the KPFM measurements, using NANOSENSORS™ Platinum Silicide ( PtSi ) AFM probes. * https://www.nanosensors.com/uploads/media/files/0001/05/46425f364ed11a0a90b5c6db11118a319a4b4705.pdf Please have a look at the NANOSENORS blog for the full citation and a direct link to the full article. #KPFM #AtomicForceMicroscopy #ScanningProbeMicroscopy

DNA origami nanostructures are widely employed in various areas of fundamental and applied research. Due to the tremendous success of the DNA origami technique in the academic field, considerable efforts currently aim at the translation of this technology from a laboratory setting to real-world applications, such as nanoelectronics, drug delivery, and biosensing. While many of these real-world applications rely on an intact DNA origami shape, they often also subject the DNA origami nanostructures to rather harsh and potentially damaging environmental and processing conditions.* In their article “Effect of Staple Age on DNA Origami Nanostructure Assembly and Stability” Charlotte Kielar, Yang Xin, Xiaodan Xu, Siqi Zhu, Nelli Gorin , Guido Grundmeier, Christin Möser, David M. Smith and Adrian Keller investigate the effect of long-term storage of the employed staple strands on DNA origami assembly and stability.* Atomic force microscopy (AFM) under liquid and dry conditions was employed to characterize the structural integrity of Rothemund triangles assembled from different staple sets that have been stored at −20 °C for up to 43 months.* NanoWorld Ultra-Short Cantilevers USC-F0.3-k0.3 were the AFM probes that were used for the AFM measurements under liquid conditions.* https://www.nanoworld.com/Ultra-Short-Cantilevers-USC-F0.3-k0.3.html Please have a look at the NanoWorld blog for the full citation and a direct link to the full article. #DNA #nanotechnology #AtomicForceMicroscopy

Published new post (Nucleation in confinement generates long-range repulsion between rough calcite surfaces) on NANOSENSORS Blog Fluid-induced alteration of rocks and mineral-based materials often starts at confined mineral interfaces where nm-thick water films can persist even at high overburden pressures and at low vapor pressures. These films enable transport of reactants and affect forces acting between mineral surfaces. However, the feedback between the surface forces and reactivity of confined solids is not fully understood.* In “Nucleation in confinement generates long-range repulsion between rough calcite surfaces» Joanna Dziadkowiec, Bahareh Zareeipolgardani, Dag Kristian Dysthe and Anja Røyne describe how they used the surface forces apparatus (SFA) to follow surface reactivity in confinement and measure nm-range forces between two rough calcite surfaces in NaCl, CaCl2, or MgCl2 solutions with ionic strength of 0.01, 0.1 or 1 M.* Roughness evolution with time of single, unconfined calcite films in salt solutions was analyzed by Atomic Force Microscopy using NANOSENSORS™ uniqprobe qp-SCONT AFM probes to image the surfaces in contact mode.* https://www.nanosensors.com/uniqprobe-uniform-quality-spm-probe-soft-contact-mode-qp-scont Please have a look at the NANOSENSORS blog for the full citation and a direct link to the full article. #AtomicForceMicroscopy #ChemicalPhysics #RoughnessCharacterization

Real-space images of polymers with sub-molecular resolution could provide valuable insights into the relationship between morphology and functionality of polymer optoelectronic devices, but their acquisition is problematic due to perceived limitations in atomic force microscopy (AFM).* In the article “Ultra-high resolution imaging of thin films and single strands of polythiophene using atomic force microscopy” Vladimir V. Korolkov, Alex Summerfield, Alanna Murphy, David B. Amabilino, Kenji Watanabe, Takashi Taniguchi and Peter H. Beton show that individual thiophene units and the lattice of semicrystalline spin-coated films of polythiophenes (PTs) may be resolved using AFM under ambient conditions through the low-amplitude (≤ 1 nm) excitation of higher eigenmodes of a cantilever.* They authors demonstrate that the use of higher eigenmodes in tapping-mode ambient AFM can be successfully employed to characterize both individual polymer strands down to a single-atom level and also the ordering of a semi-crystalline polymer with technological relevance. The combination of AFM and solution deposition provides a simple and high-resolution approach to characterizing the structure of polymers.* The use of NanoWorld Arrow-UHF high frequency AFM probes at their first eigenmode of ~1.4 MHz is mentioned.* https://www.nanoworld.com/ultra-high-frequency-tapping-mode-afm-tip-arrow-uhf Please have a look at the NanoWorld blogpost for the full citation and a direct link to the full article. #AtomicForceMicroscopy #ImagingTechniques #MolecularSelfAssembly

Ferroelectricity-free lead halide perovskites – NANOSENSORS BlogSun Jul 21 2019

Published new post (Ferroelectricity-free lead halide perovskites) on NANOSENSORS Blog In the recent publication “Ferroelectricity-free lead halide perovskites” Andrés Gómez, Qiong Wang, Alejandro R. Goñi, Mariano Campoy-Quilesa and Antonio Abate describe how they employed direct piezoelectric force microscopy ( DPFM ) to examine whether or not lead halide perovskites exhibit ferroelectricity.* Their article aims to provide a deeper understanding of the fundamental physical properties of the organic–inorganic lead halide perovskites and solves a longstanding dispute about their non-ferroelectric character: an issue of high relevance for optoelectronic and photovoltaic applications.* In the course of their research in which besides using DPFM, they also employed piezoelectric force microscopy ( PFM ) and electrostatic force microscopy ( EFM ), they could demonstrate the non-ferroelectricity of lead halide perovskites. * The PFM images were acquired using a PtIr coated NANOSENSORS PPP-EFM AFM probe. https://www.nanosensors.com/PointProbe-Plus-Electrostatic-Force-Microscopy-PtIr5-Coating-afm-tip-PPP-EFM Please have a look at the NANOSENORS blog for the full citation and a direct link to the full article. #perovskite #photovoltaics #ElectrostaticForceMicroscopy #AFMprobes
