DOI: 10.1007/s10965-019-1735-3
Abstract: Inspired by the chlorophyll-protein complex in photosynthesis, a core–shell hybrid micelle was prepared from poly(ethylene glycol)-block-poly(4-vinylpyridine) (PEG-b-P4VP), zinc tetrakis(4-sulfonatophenyl) porphyrin (ZnTPPS), and silver nanoparticles (AgNPs). In the micellar core, AgNPs and ZnTPPS were dispersed through… read more here.
