New Polymer Synthetic Strategy

Picture

​We aim to develop a scalable and concise synthetic strategy to prepare functionalized polyesters from amino acids through controlled living polymerization of O-carboxyanhydrides monomers and other cyclic monomers.

Light-triggered Drug Delivery

Picture

​The ability to trigger drug release from a device (i.e. on-demand drug delivery) can enable control over the exact timing (onset and offset) and magnitude of therapeutic effect, and also provide spatio-temporal control which can enhance the therapeutic index. We aim to develop nanoparticulate triggerable drug delivery systems that respond to external energy sources for drug delivery and tissue penetration. This can be potentially applied in ocular drug delivery and chemotherapy.
