Millisecond dynamics of an unlabeled amino acid transporterMon Nov 30 2020

Excitatory amino acid transporters (EAATs) are important in many physiological processes and crucial for the removal of excitatory amino acids from the synaptic cleft.*

In the article “Millisecond dynamics of an unlabeled amino acid transporter “ Tina R. Matin, George R. Heath, Gerard H. M. Huysmans, Olga Boudker and Simon Scheuring develop and apply high-speed atomic force microscopy line-scanning (HS-AFM-LS) combined with automated state assignment and transition analysis for the determination of transport dynamics of unlabeled membrane-reconstituted GltPh, a prokaryotic EAAT homologue, with millisecond temporal resolution.*

Among the bulk and single-molecule techniques, high-speed atomic force microscopy ( HS-AFM ) stands out with its ability to provide real-time structural and dynamical information of single molecules. HS-AFM images label-free molecules under close-to-physiological conditions with ~0.1 nm vertical and ~1 nm lateral imaging resolution. Furthermore, HS-AFM has typically ~100 ms temporal resolution, giving access to structure–dynamics relationship of proteins, though the achievable imaging speed depends on sample characteristics like scan size and surface corrugation.

NANOSENSORS Nanoscale Charge Accumulation and Its Effect on Carrier Dynamics in Tri-cation Perovskite Structures - news

Nanoscale Charge Accumulation and Its Effect on Carrier Dynamics in Tri-cation Perovskite StructuresThu Nov 26 2020

Nanoscale investigations by scanning probe microscopy have provided major contributions to the rapid development of organic–inorganic halide perovskites (OIHP) as optoelectronic devices. Further improvement of device level properties requires a deeper understanding of the performance-limiting mechanisms such as ion migration, phase segregation, and their effects on charge extraction both at the nano- and macroscale.

In the article “Nanoscale Charge Accumulation and Its Effect on Carrier Dynamics in Tri-cation Perovskite Structures” David Toth, Bekele Hailegnaw, Filipe Richheimer, Fernando A. Castro, Ferry Kienberger, Markus C. Scharber, Sebastian Wood and Georg Gramse describe how they studied the dynamic electrical response of Cs0.05(FA0.83MA0.17)0.95PbI3–xBrx perovskite structures by employing conventional and microsecond time-resolved open-loop Kelvin probe force microscopy (KPFM).

NanoWorld Molecular and nanoscale evaluation of N-cadherin expression in invasive bladder cancer cells under control conditions or GW501516 exposure - news

Molecular and nanoscale evaluation of N-cadherin expression in invasive bladder cancer cells under control conditions or GW501516 exposureMon Oct 26 2020

In the article “Molecular and nanoscale evaluation of N-cadherin expression in invasive bladder cancer cells under control conditions or GW501516 exposure” Céline Elie-Caille, Isabelle Lascombe, Adeline Péchery, Hugues Bittard and Sylvie Fauconnet, describe how they aimed at exploring the expression level of N-cadherin in invasive bladder cancer cells upon GW501516 exposure by both molecular biology techniques such as RTqPCR and Western blotting and Atomic Force Microscopy ( AFM ) using NanoWorld Pyrex-Nitride silicon nitride PNP-TR AFM tips functionalized with a monoclonal antibody directed against this adhesion molecule. *

Yeast Nanometric Scale Oscillations Highlights Fibronectin Induced Changes in C. AlbicansMon Oct 19 2020

Yeast resistance to antifungal drugs is a major public health issue. Fungal adhesion onto the host mucosal surface is still a partially unknown phenomenon that is modulated by several actors among which fibronectin plays an important role. Targeting the yeast adhesion onto the mucosal surface could lead to potentially highly efficient treatments. *
In the article “Yeast Nanometric Scale Oscillations Highlights Fibronectin Induced Changes in C. Albicans” Anne-Céline Kohler, Leonardo Venturelli, Abhilash Kannan, Dominique Sanglard, Giovanni Dietler, Ronnie Willaert and Sandor Kasas, explore the effect of fibronectin on the nanomotion pattern of different Candida albicans strains by atomic force microscopy ( AFM )-based nanomotion detection and correlated the cellular oscillations to the yeast adhesion onto epithelial cells. *

NanoWorld Electrochromic switching of tungsten oxide films grown by reactive ion-beam sputter deposition - news

Electrochromic switching of tungsten oxide films grown by reactive ion-beam sputter depositionTue Oct 13 2020

The building sector and within it the class of so-called smart windows plays an important role in terms of energy saving potential. Chromogenic thin films are crucial building blocks in smart windows to modulate the flux of visible light and heat radiation into buildings.
In “Electrochromic switching of tungsten oxide films grown by reactive ion-beam sputter deposition” Mario Gies et al. describe how Tungsten oxide thin films were grown by ion-beam sputter deposition (IBSD) and then show the possibility of influencing samples characteristics by using different preparation parameters. This allows to tune the elemental composition, optical properties or to influence the structure and the degree of crystallization in the resulting thin films.
NanoWorld® Pointprobe® SEIHR AFM probes designed for soft non-contact mode imaging were used for the AFM investigations described in the cited article. https://www.nanoworld.com/pointprobe-seiko-instruments…
