Effect of SPIO-clustering on thermodynamic stability of PEG-PLA polymeric micelles. Fluorescence emission spectra (lex=399 nm) of 1,3-di(1,1′-pyrenyl)propane in SPIO-free micelles (A) and SPIO-loaded micelles (C). Fluorescence intensity ratio of excimer (lem = 478 nm) to monomer (lem = 377 nm) of 1,3-di (1,1′-pyrenyl)propane (Ie /Im) of SPIO-free micelles (B) and SPIO-micelles (D) at different temperatures
