Block copolymers were utilized to generate aqueous multicompartment micelles to encapsulate dyes capable of photosensitizing singlet oxygen. The microheterogeneous singlet oxygen concentration is due to the dye's specific preference to the micellar hydrophobic, hydrophilic, or fluorophilic compartments. Singlet oxygen concentrations were determined by trap-and-trigger probes tuned for specific binding to the respective micellar compartments.
