Professor Leong's research interest focuses on biomaterials design, particularly for synthesis of nanoparticles for gene and immunotherapy, and nanofibers for regenerative medicine applications.

Biomaterials Design:

• design of self-assembled fibers for tissue engineering
• synthesis of new biodegradable polymers and new polyelectrolytes for drug and gene delivery applied to tissue engineering
• synthesis of thermosensitive hydrogels for tissue engineering

Controlled Drug and Gene Delivery:

• oral gene delivery for hemophilia A and B
• non-viral gene delivery to the GI tract, bladder, and CNS
• oral delivery of antigen genes for vaccination

Tissue Engineering:

• study of interaction of stem cells with biofunctional polymeric surface
• expansion of hematopoietic stem cells
• nerve guidance channels with drug and gene delivery functions
• microencapsulation of stem cells and genetically-engineered cells
• development of bioartificial nucleus pulposus device
• study of interaction of SMC and neuronal stem cells with synthetic nanostructured biomaterials
