The porphyrin-coated AuNPs were characterized by UV-Vis, TEM, XRD, and XPS analyses. The tetradentate porphyrin-AuNPs size is within a range of 5-15 nm in diameter with exotic shapes. The plausible network formation for AuNP@p-TPP-SAc and the capping structure of the AuNP@m-TPP-SAc have been suggested.en10.1007/s11051-011-0636-0info:eu-repo/semantics/closedAccessPorphyrinGold nanoparticlesThioacetateXPSTEMBiomedical applicationsArticle131272197228Q2WOS:000298056100095Q1
