A versatile and accessible polymer coating for functionalizable zwitterionic quantum dots with high DNA grafting efficiency

Chem Commun (Camb). 2019 Sep 21;55(74):11067-11070. doi: 10.1039/c9cc04856a. Epub 2019 Aug 27.

Abstract

Efficient and versatile functionalization of poly(anhydride maleic-alt-isobutylene) (PIMA), with economical commercial reagents, results in the one-step/one-day production of a copper-free click chemistry-ready carboxybetaine-like coating for quantum dots (QDs). The QDs are bright and stable in aqueous media and easily grafted with DNA with >95% efficiency.
