The photobehavior of merocyanine 540 (MC) was studied in homogeneous media (ethanol, buffer and glycerol), and in microheterogenous systems (Triton X-100 micelles and in the presence of human serum albumin) using stationary and time-resolved techniques. Merocyanine 540 in aqueous solution mostly forms aggregates, which in the presence of Triton X-100 or HSA are disaggregated. The extent of binding to HSA and its characteristics were estimated from dye absorption and fluorescence changes… CONTINUE READING
