Evaluation of singlet oxygen production by the NF. a phosphorescence decays of singlet oxygen (at 1270 nm) sensitized by NF with HPPH only and HPPH/JB7-08 NF. Two concentration of NPs_D2 was used for preparation of each NF. b ABDA bleaching as a measure of the singlet oxygen generation by ABDA in water, and in suspensions of HPPH, HPPH/JB7-08 and HPPH/JB17-08 NFPPH loaded to NPs and NF
