Why use polymer-siRNA conjugate
Due to its high hydrophilicity, the delivery efficiency and bioavailability of siRNA are poor. Combining with polymers (especially PEG) can extend the half-life of drugs in the blood and enhance pharmacokinetic properties.
For polymer-siRNA bioconjugate systems, the potential to use multiple different components enables safe and effective delivery of siRNA to target cells. These basic ingredients include ligands for targeting, internal soluble components for endosomal escape, PEG chains that prolong blood retention, and potentially hydrophobic lipids.
