A: fluorescence quenching study of CPT-VE or CPT-S-S-VE nanoformulations. B: quantitation of the fluorescence decrease in CPT-VE or CPT-S-S-VE nanoassemblies compared to the free CPT-VE or CPT-S-S-VE. C: Fmoc Fluorescence. D: reduction of Fmoc fluorescence intensity after incorporating CPT-VE or CPT-S-S-VE into PEG5K-Fmoc-VE2.
