Fluorescence spectra of polySt-poly(NIPAM-co-AA) NPs post-loaded with HPPH and dyes. a HPPH fluorescence emission (excitation at 400 nm). b Fluorescence decays for HPPH in organic solvent (DMF) or in NF, post-loaded alone or with two different NIRFDs. c fluorescence of NIRFDs post-loaded to NF alone or in combination with HPPH (excitation at 808 nm)
