Fabrication of folate bioconjugated near-infrared fluorescent silver nanoclusters for targeted in vitro and in vivo bioimaging†
Abstract
Thiolpolyethyleneimine stabilized silver nanoclusters (SH-PEI-AgNCs) with intense NIR fluorescence and chemical stability were fabricated in aqueous solution. The SH-PEI-AgNCs were subsequently bioconjugated with folate for targeted in vitro and in vivo bioimaging.
