Adsorption of SARS-CoV-2 Spike Protein S1 at Oxide Surfaces Studied by High-Speed Atomic Force MicroscopyWed Jun 08 2022
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 spike protein subunit 1 (S1), which is the outermost point of its envelope. Understanding S1 spike protein interaction with fomite surfaces thus represents an important milestone on the road to fighting the spread of COVID-19.*
In the article “Adsorption of SARS-CoV-2 Spike Protein S1 at Oxide Surfaces Studied by High-Speed Atomic Force Microscopy “ Yang Xin, Guido Grundmeier and Adrian Keller describe how high-speed atomic force microscopy (HS-AFM) is used to monitor the adsorption of the SARS-CoV-2 spike protein S1 at Al2O3(0001) and TiO2(100) surfaces in situ. *

Today we remember the late Heinrich Rohrer.Mon Jun 06 2022
The Swiss physicist - Heinrich Rohrer, born on this date in 1933, shared half of the 1986 Nobel Prize in Physics with Gerd Binnig (on the right) for the invention of the Scanning Tunneling Microscope (STM), the daddy of the Atomic Force Microscope (AFM). Thank you for leading the way!
Novel characteristics of soluble fibrin: hypercoagulability and acceleration of blood sedimentation rate mediated by its generation of erythrocyte-linked fibersSat Jun 04 2022
Soluble fibrin (SF) in blood consists of monomers lacking both fibrinopeptides A with a minor population in multimeric clusters. It is a substantial component of isolated fibrinogen (fg), which spontaneously self-assembles into protofibrils progressing to fibers at sub-physiologic temperatures, a process enhanced by adsorption to hydrophobic and some metal surfaces.

Influence of B/N co-doping on electrical and photoluminescence properties of CVD grown homoepitaxial diamond filmsWed May 25 2022
Boron doped diamond (BDD) has great potential in electrical, and electrochemical sensing applications. The growth parameters, substrates, and synthesis method play a vital role in the preparation of semiconducting BDD to metallic BDD. Doping of other elements along with boron (B) into diamond demonstrated improved efficacy of B doping and exceptional properties.

Rapid access to discrete and monodisperse block co-oligomers from sugar and terpenoid toward ultrasmall periodic nanostructuresTue May 10 2022
Discrete block co-oligomers (BCOs) can form highly ordered ultrasmall nanostructures which can be used for lithographic templates. These nanotemplates are promising for the low-cost, large-scale, and high-throughput production of sub-10 nm nanomaterials and nanodevices. However, work-intensive synthetic routes can be an obstacle to their practical application. Read more...
