Abstract

A simple method for the synthesis of lipophilic Ag NPs have been developed. The coated Ag NPs have been entrapped into a FDA-approved and targetable PEG-based polymeric nanoparticles, and this nanocarrier has been conjugated with the peptide chlorotoxin. Uptake experiments have shown a cell-specific recognition of the Ag-1-PNPs-Cltx on U87MG cell lines in comparison to Balb/3T3. The uptake of Ag into the cells was quantified and an interesting cytotoxic effect (IC50 = 45 μM) has been found on glioblastoma cell lines.
