Peptide position determines whether gold nanoparticles branch or stay spherical

The position of biomineralization peptides within liposomes can influence how gold nanoparticles grow, reports a research team from the Institute of Science Tokyo. Peptides localized at the membrane interface promote branched structures, while those confined to the liposome interior favor spherical nanoparticles. The findings offer a new strategy for controlling nanoscale reaction environments in nanoparticle synthesis.
