摘要: Polyvalent oligonucleotide gold nanoparticle conjugates (DNA-AuNPs) have appealing properties for drug delivery applications, including high cellular uptake in a variety of cell types, no demonstrated toxicity inherent to the conjugate, and resistance to enzymatic degradation. In this chapter, the authors have combined the properties of DNA-AuNPs and platinum (IV) prodrugs into a single agent for drug delivery. DNA-AuNPs were synthesized, characterized, and tested in vitro as carriers for Pt (IV) prodrugs. The conjugate was …
