Research Interests

General research interests are molecular design, synthesis, modification, and self-assembly of smart polymers for biomedical and optoelectronic applications, including Biomaterials, Molecular Biosensors, Smart Gels, Optoelectronic Polymers, Conjugated Polymers, Block Copolymers, Organic-inorganic Hybrid Materials, Photovoltaic Cells, and Self-assembly. Currently we are studying the following areas:

Negative Index Materials: This project focuses on the development of metamaterials that exhibit negative refractive index (NRI) at visible/infrared wavelength ranges via the rigid rod-flexible coil block copolymer-directed nanoparticles(NPs) assembly. The unit cell size of metamaterials, defined by the molecular structure of block copolymer and shape/size of NPs, governs their electromagnetic properties. Selective affinity between rod block and NPs can be used to confine the NPs at rod block domain. This simple solution cast method can provide bottom-up assembly for metamaterial and eliminate complicated and tedious fabrication methods.

Biosensors: Sensitivity and selectivity are the most important parameters of a sensor. Nature provides high fidelity in biosynthesis. The unique combination of this specificity of the bio-system and the tunable properties of synthetic polymers would be a promising direction toward molecular sensors with high selectivity and sensitivity. We are developing molecular biosensors through bio-/synthetic hybrid systems.

Photovoltaic Cells: Much effort has been made to convert abundant solar energy into useful electricity. The solar cells made of inorganic semiconductors require stringent manufacturing processes and high cost that are not suitable for large area application. Conjugated polymer (CP)-based solar cells are attractive alternatives due to easy processability and the tunable optoelectronic properties. Hybrid composites of conjugated block copolymers and inorganic nanoparticles are currently under investigation.
