Tip wear and tip breakage in high-speed atomic force microscopesTue Nov 05 2019

High speed scanning (HSS) AFM tests with our ContDLC AFM probes at velocities up to 1mm/s demonstrate the high durability of our diamond-like carbon coated tips. Scanning hard surfaces with sharp, steep edges at ultrahigh scan rates increases the danger of sudden apex breakage due to sudden high lateral forces. So, please do not HSS our TipCheck! :) Learn more in this in-depth study published in the Ultramicroscopy journal. #AFMProbes #AtomicForceMicroscopy #HighSpeedScanning

Analysis of long dsRNA produced in vitro and in vivo using atomic...Tue Oct 29 2019

New post - Analysis of long dsRNA produced in vitro and in vivo using atomic force microscopy in conjunction with ion-pair reverse-phase HPLC (https://www.nanoworld.com/…/analysis-of-long-dsrna-produce…/) has been published on NanoWorld Blog.

Long double-stranded (ds) RNA is emerging as a novel alternative to chemical and genetically-modified insect and fungal management strategies. The ability to produce large quantities of dsRNA in either bacterial systems, by in vitro transcription, in cell-free systems or in planta for RNA interference applications has generated significant demand for the development and application of analytical tools for analysis of dsRNA.*

In their article “Analysis of long dsRNA produced in vitro and in vivo using atomic force microscopy in conjunction with ion-pair reverse-phase HPLC” Alison O. Nwokeoji, Sandip Kumar, Peter M. Kilby, David E. Portwood, Jamie K. Hobbs and Mark J. Dickman have utilised atomic force microscopy (AFM) in conjunction with ion-pair reverse-phase high performance liquid chromatography (IP-RP-HPLC) to provide novel insight into dsRNA for RNAi applications.*

The AFM analysis enabled direct structural characterisation of the A-form duplex dsRNA and accurate determination of the dsRNA duplex length.*

The work presented in this study demonstrates the ability of AFM in conjunction with IP RP HPLC to rapidly assess sample heterogeneity and provide important structural information regarding dsRNA.*

NANOSENSORS Nonlinear Biomechanical Characteristics of Deep Deformation of Native RBC Membranes in Normal State and under Modifier Action - news

Nonlinear Biomechanical Characteristics of Deep Deformation of Native RBC Membranes in Normal State and under Modifier ActionMon 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

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

Direct evidence for grain boundary passivation in Cu(In,Ga)Se2 solar cells through alkali-fluoride post-deposition treatmentsTue Sep 10 2019

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
