Adsorption of SARS-CoV-2 Spike Protein S1 at Oxide Surfaces Studied by High-Speed Atomic Force Microscopy

The ongoing coronavirus disease 2019 (COVID-19) pandemic caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) represents a serious threat to the health of millions of people. Respiratory viruses such as SARS-CoV-2 can be transmitted via airborne and fomite routes. The latter requires virion adsorption at abiotic surfaces and most likely involves the SARS-CoV-2 … Continue reading Adsorption of SARS-CoV-2 Spike Protein S1 at Oxide Surfaces Studied by High-Speed Atomic Force Microscopy

Actin filaments on Mica with APTES

Courtesy of Prof. Noriyuki Kodera, nanoLSI, Kanazawa University, Japan we could upload two new images and a very nice High Speed Atomic Force Microscopy (HS-AFM) video of Actin filaments on Mica with APTES to the image gallery and the video gallery on https://www.highspeedscanning.com/. NanoWorld USC-F1.2-k0.15 Ultra-Short AFM cantilevers [C = 0.15 N/m; fo = 1200 … Continue reading Actin filaments on Mica with APTES

Correlation of membrane protein conformational and functional dynamics

Membrane proteins (MPs) reside in the plasma membrane and perform various biological processes including ion transport, substrate transport, and signal transduction.* Function-related conformational changes in membrane proteins occur in times scales ranging from nanoseconds to seconds.* Obtaining time-resolved dynamic information of MPs in their membrane environment is still a major challenge.* Although High Speed Atomic … Continue reading Correlation of membrane protein conformational and functional dynamics
