Mechanistic insight into the singlet oxygen-triggered expansion of hypoxia-responsive polymeric micelles†
Abstract
Nitroimidazole-bearing nanomedicine has been popular as a hypoxia-responsive platform for on-demand drug delivery. We report the singlet oxygen-responsive property of nitroimidazole-containing micelles and the corresponding reaction mechanism, which would pave the way for developing a dual hypoxia- and singlet oxygen-sensitive drug delivery nanoplatform based on a simple nitroimidazole moiety.
