  2. Polymers


The utility of polymers to function as intracellular delivery systems for nucleic acids has been studied for several decades. For instance, cationic polymers are able to condense nucleic acids into polyplexes via electrostatic interactions, enhancing cellular uptake and endosome escape. Notably, the physiochemical properties of polymers (charge, degradability and molecular weight) can be carefully adjusted through bottom-up chemical synthesis. Up to now, cyclodextrin polymer (CDP)-based nanoparticles have entered clinical trials for siRNA delivery.
