ATP responsive DNA nanogels grown on biocompatible branches for anticancer drug delivery.
SOFT MATTER(2019)
摘要
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.
