Researchers from the Institute of Science Tokyo report that the position of biomineralization peptides within liposomes influences gold nanoparticle growth. Peptides at the membrane interface promote branched structures, while those confined to the liposome interior favor spherical nanoparticles. The team presents this as a new strategy for controlling nanoscale reaction environments.
Our view
This identifies a spatial parameter for tuning nanoparticle shape, though the finding is presented as a single team's report.
What the reporting says: The position of biomineralization peptides within liposomes can influence how gold nanoparticles grow, with peptides at the membrane interface promoting branched structures and those confined to the liposome interior favoring spherical nanoparticles.
