ATP responsive DNA nanogels grown on biocompatible branches for anticancer drug delivery

Soft Matter. 2019 May 8;15(18):3655-3658. doi: 10.1039/c9sm00480g.

Abstract

We developed biocompatible ATP responsive DNA nanogels, by grafting DNA strands on carboxymethyl chitosan polymer chains, and then hybridizing with ATP aptamers to form core-shell nanogels. The DNA duplex structure could embed DOX in the G-C sequences, and realize simultaneous sol-gel transition and DOX release when suffering enrich ATP in tumor cells.
