Abstract

We introduce a new set of multifunctional metal-coordinating polymers as ligands for the surface functionalization of three different inorganic nanocrystals: luminescent quantum dots (QDs), magnetic iron oxide nanocrystals and metal gold nanoparticles. The ligand design relies on the introduction of a large but controllable number of anchoring groups, hydrophilic moieties and reactive functionalities all in the same polymer chain, via a one-step nucleophilic addition reaction. Nanocrystals capped with these polymer ligands exhibit long-term stability over a broad range of biological conditions. Furthermore, when zwitterion groups are introduced as hydrophilic blocks, this yields a compact ligand coating that allows conjugation of biomolecules to the nanocrystals via metal-histidine self-assembly. The resulting hydrophilic nanocrystals have been used to develop a few specific sensing platforms targeting soluble iron ions and cysteine.
