Fig. 2From: Core–shell polymeric nanoparticles co-loaded with photosensitizer and organic dye for photodynamic therapy guided by fluorescence imaging in near and short-wave infrared spectral regionsAbsorption spectra of NF: a NPs_D2 post-loaded with HPPH alone or with JB7-08. b NPs_D2 post-loaded with HPPH alone or with JB17-08. Spectra were acquired 24 h after addition of HPPH and NIRFDs to water suspension of polySt-poly(NIPAM-co-AA) NPsBack to article page
