Aptamer-targeted hyperbranched polymers: towards greater specificity for tumours in vivo

Chem Commun (Camb). 2013 May 10;49(37):3836-8. doi: 10.1039/c3cc00127j.

Abstract

Hyperbranched polymers conjugated to a peptide-aptamer were prepared using a combination of RAFT polymerisation and click chemistry for targeting tumour cells in vivo. The polymers showed enhanced cell-uptake in vitro (compared to unconjugated polymer) while excellent specificity for solid tumours was observed in vivo using a mouse model of melanoma.
