A recent study published in the journal Science brings a detailed chemical and molecular perspective on the improved evasion of antibodies against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and the retention of strong interactions with the receptor as two principal factors underneath the notorious transmissibility of the SARS-CoV-2 Omicron variant.

Scientists at Scripps Research have devised a method that may be able to shortcut one of the big steps in modern vaccine development.

Electron microscopy (EM) is an experimental method employed to capture high-resolution images of microscopic samples. It is a powerful technique to study the detailed structure of biological specimens such as tissues and cells.

In a new study, researchers used cryogenic electron microscopy (cryo-EM) analysis to capture the open and closed states of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variant’s spike protein.

Catalyst surfaces have rarely been imaged in such detail before. And yet, every single atom can play a decisive role in catalytic activity. A German-Chinese research team has visualised the three ...

A recent paper that was published in the Talanta journal dedicated to original reports in pure and applied analytical chemistry presents for the first time the combination of two different nanomaterials – gold nanomaterials (AuNMs) and CDs for the development of an improved electrochemiluminescence (ECL) DNA biosensor.

An interesting preprint research paper describes structural changes resulting from the multiple mutations found in the recent Omicron variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). SARS-CoV-2 is the causative agent behind the coronavirus disease 2019 (COVID-19) pandemic. In addition, the research describes the consequent effects of these changes on Omicron’s infectivity and immune evasion capabilities.

Researchers investigated the potency of trimeric human nephrocystin SH3, TriSb92, a domain-derived antibody, against a conserved region in the receptor-binding domain (RBD) of the spike protein in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants of concern.
