The absorption and fluorescence of PPA-protected Ag NDs (PPA@AgNDs) were assessed with a spectrophotometer and a spectrofluorometer, correspondingly. The morphology of PPA@AgNDs ended up being characterized by high-angle annular dark-field (HAADF) scanning transmission electron microscopy (STEM). The biocompatibility of PPA@AgNDs ended up being assessed by tetrazolium (MTT)-based assay. PolyLys-Cys-SH (sequence KKKKKKC) peptides were conjugated to PPA@AgNDs via h
