All bound up: A small variant of protein A (red; see picture) was used as a biotemplate for the synthesis and biofunctionalization of gold nanoparticles (AuNPs). These functionalized AuNPs were able to bind to antibodies (green blocks, trastuzumab; TZ) with a defined orientation, thus showing promise as bio-nanoparticle systems suitable for selective cell labeling by membrane-receptor-specific recognition.
