A heterobifunctional reactive oxygen species (ROS)-responsive linker for directed drug assembly onto and delivery from a quantum dot (QD) nanoparticle carrier was synthesized and coupled to doxorubicin using N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (EDC)/sulfo–NHS coupling. The doxorubicin conjugate was characterized using 1H NMR and LC-MS and subsequently reacted under conditions of ROS formation (Cu2+/H2O2) resulting in successful and rapid thioacetal oxidative cleavage, which was monitored using 1H NMR.
