Metallized scaffolds: Oligoproline scaffolds that are functionalized with aldehyde groups have been shown to control the size of silver nanoparticles that are formed in the Tollens reaction. The size of the nanoparticles correlates linearly with the length of the scaffold and the oxidation of the aldehyde moieties during the reaction helps to stabilize the nanoparticles through coordination to the newly formed carboxylic acid groups.
Functionalized oligoproline scaffolds that have defined lengths have been shown to control the size of silver nanoparticles that are formed in the Tollens reaction. In their Communication on H. Wennemers et al. demonstrate the correlation between the molecular dimensions of the peptide scaffold and the size of the nanoparticles that are produced in an approach that opens the door to precise control of the size of metal nanoparticles.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
