Release profile of m-PEG-RB encapsulated in photoresponsive Ac-Dex particles either in the dark (closed circles) or exposed to a UV light (open squares; exposure time: 1 min, lightning bolts). The amount of PEG-RB in the each supernatant sample was determined by measuring the emission at 580 nm (λex = 540 nm) and fitting to a calibration curve.
