Published new post (Visualizing the bidirectional optical transfer function for near-field enhancement in waveguide coupled plasmonic transducers) on NANOSENSORS™ Blog In their article “Visualizing the bidirectional optical transfer function for near-field enhancement in waveguide coupled plasmonic transducers” Lauren M. Otto, D. Frank Ogletree, Shaul Aloni, Matteo Staffaroni, Barry C. Stipe and Aeron T. Hammack describe how visualizations of the near-field modes in the region of a plasmonic device were created using scattering scanning near-field optical microscopy and scanning electron microscopy cathodoluminescence with both showing a strong correspondence to multiphysical numerical modeling of the devices under interrogation. The sSNOM measurements shown in this article were performed with NANOSENSORS™ AdvancedTEC™ ATEC-NC tip-view AFM probes.https://www.nanosensors.com/advanced-tip-at-the-end-of-the-… Please have a look at the NANOSENSORS™ blog for the full citation and a direct link to the full article.#ScatteringScanningNearFieldOpticalMicroscopy #AtomicForceMicroscopy #AFM

Published new post (From Polymer to Magnetic Porous Carbon Spheres: Combined Microscopy, Spectroscopy, and Porosity Studies) on NANOSENSORS Blog In their research paper “From Polymer to Magnetic Porous Carbon Spheres: Combined Microscopy, Spectroscopy, and Porosity Studies” Federico Cesano, Sara Cravanzola, Valentina Brunella, Alessandro Damin and Domenica Scarano, after having first reported the preparation of polymer waste-derived microporous carbon microspheres (SBET ~800 m2/g) 100–300 μm in size, investigate the morphology, porous texture and the surface properties of carbon and of magnetic carbon microspheres by multiple techniques.* The multi-technique methodology they used aims at an extensive description of the different characteristics of activated carbons with magnetic properties. For the Atomic Force Microscopy described in this paper NANOSENSORS™ SSS-MFMR AFM probes for high resolution magnetic force imaging were used for the topography images as well as the MFM imaging. https://www.nanosensors.com/supersharpsilicon-magnetic-force-microscopy-reflex-coating-afm-tip-SSS-MFMR Please have a look at the NANOSENSORS Blog for the full citation and a direct link to the full article. #AmorphousCarbon #Fe3O4 #nanoparticles #AtomicForceMicroscopy

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

Quantifying the adaptive mechanical behavior of living cells is essential for the understanding of their inner working and function.* In their article “Simultaneous Quantification of the Interplay Between Molecular Turnover and Cell Mechanics by AFM–FRAP” Mark Skamrahl, Huw Colin‐York, Liliana Barbieri and Marco Fritzsche use a combination of atomic force microscopy and fluorescence recovery after photobleaching is introduced which offers simultaneous quantification and direct correlation of molecule kinetics and mechanics in living cells.* Simultaneous quantification of the relationship between molecule kinetics and cell mechanics may thus open up unprecedented insights into adaptive mechanobiological mechanisms of cells.* For the AFM nanoindentation tests described in their publication the authors used NanoWorld Arrow-TL2 tipless cantilevers that were functionalized with a polystyrene bead with 5 µm radius.* https://www.nanoworld.com/array-of-2-tipless-cantilevers-arrow-tl2-afm-tip Please have a look at the NanoWorld blog for the full citation and a direct link to the full article. #CellMechanics #biomechanics #nanoindentation
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

New post - Real-Time Observation of Fibrous Zeolites Reactivity in Contact with Simulated Lung Fluids (SLFs) Obtained by Atomic Force Microscope (AFM) has been published on NanoWorld Blog.
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.
