Reversible light-controlled fluorescence switch of block polymer-grafted carbon dots and cellular imaging

Abstract

A novel kind of aggregation-induced emission (AIE) nanoparticles, which are carbon dots (CDs) grafted with block polymer of tetraphenylethylene, spiropyran and N-isopropylacrylamide (CD-g-poly((TPE-co-SPA)-block-NIPAM)) was synthesized. The CD-g-poly((TPE-co-SPA)-block-NIPAM) nanoparticles can emit...
