From: Uptake of Chlorin e6 Photosensitizer by Polystyrene-Diphenyloxazole-Poly(N-Isopropylacrylamide) Hybrid Nanosystem Studied by Electronic Excitation Energy Transfer

Fig. 6

Fluorescence spectra of chlorin e6 free and added to PS-PPO-PNIPAM hybrid NS (measured in 0, 5, 10, 20, 40, and 80 min after addition). Excitation wavelengths are 250 and 400 nm; 50 mM Tris-HCl buffer, pH 7.2, was used as solvent. Short-dashed arrows indicate spectra excited at 250 and 400 nm. Solid arrow indicates the increasing time (t) after the addition of chlorin e6 for the spectra excited at 250 nm
