The data underlines the paper Thioanisole Ester Based Logic Gate Cascade to Control ROS-triggered Micellar Degradation. In this work, thioanisole ester based block copolymers have been used to obtain micelles in aqueous environment. The thioanisole ester moiety has been found responsive to reactive oxygen species. Therefore the micellar structures have been investigated as ROS- responsive drug delivery and release systems. The data sets have been obtained studying this system with several techniques (NMR, DLS, TEM, Fluorescence Spectroscopy).
