Bacteria and archaea use protein filament systems to organize cellular processes in time and space. Filaments can act as static scaffolds or as dynamic motors. In some cases, these filament systems ...

Emulating physiological T-cell activation. Scanning electron micrograph of a dense cluster of T cells interacting with artificial antigen-presenting cell scaffolds (pseudocolored). See Zhang et al.

This is a false color scanning electron micrograph of a T cell (green) on an array of clusters of T cell receptor ligands (not visible) bound to gold-palladium nanoparticles (gold, there are seven in ...

An enzymic electric cell was constructed in which the anode was composed of a zinc plate inserted in aqueous NH4Cl solution and the cathode was composed of an electrode made of a glassy carbon stick ...
