摘要: The growing utility of semiconductor quantum dots (QDs) in biochemical and cellular research necessitates, turn, continuous development surface functionalizing ligands to optimize their performance for ever more challenging diverse biological applications. Here, we describe a new class multifunctional polymeric as stable, compact high affinity alternative multidentate thiolated molecules. are designed with poly(acrylic acid) backbone where pyridines used anchoring groups that not sensitive degradation by air light, along short poly(ethylene glycol) (PEG) pendant which coincorporated aqueous solubility, biocompatibility colloidal stability. percentages each the latter functional controlled during initial synthesis incorporation carboxyl serve chemical handles subsequent covalent modification QD surface. A detailed physicochemical characterization indi...
