Research Abstract

Here, we synthesized dextrans modified with trivalent cationic or anionic groups. Aqueous solutions of the cationic and anionic dextrans were then mixed resulting in the formation of polyion complex nanogels (PIC-NGs), which have physically crosslinked salt bridges formed between the cationic and anionic groups.
We have designed biotinylated polymers as synthetic receptors that have multiple alkyl groups for endocytotic delivery of target proteins. The polymers were stably attached to a cell surface via multivalent anchoring. The presented biotin was bound to streptavidin (SA) on the cell surface, and, via an endocytotic pathway, the cell rapidly internalized the biotinylated polymer/SA complex.
