Research Interests
Research in the Xu Laboratory utilizes organic synthesis and polymerization methodologies to create next-generation advanced functional materials for electronic and biomedical applications.
Research interests lie at the interface of organic chemistry, polymer materials, soft matter nanotechnology, and biomedical engineering. We leverage our expertise in molecular design, synthesis, self-assembly, and development of advanced characterization strategies, to create new soft functional materials while controlling their dynamic behaviors in bulk states and interfacial properties between materials and biological systems.
The current ongoing research projects are broadly in Twisted but Conjugated pi-molecules as n-type Semiconductors: Molecular Design, Synthesis, Characterization and Functions (area 1); Organic Luminescent Functional Materials for the Next-Generation Optoelectronics and Biosensors (area 2); Engineering Smart Zwitterionic Biomaterials to Bridge the Bio-Electronic Interface (area 3); Advanced Smart Materials for Additive Nanomanufacturing (area 4).
The overall goal is to integrate fundamental research in novel soft matter nanotechnology and biomedical engineering with the creation of multifunctional polymers/macromolecules for advanced technologies to address problems related to energy, environment and healthcare.
Given the interdisciplinary nature of our work, students and researchers in the Xu Lab will receive broad-based training that starts from molecular design, multiple-steps organic synthesis, polymerization methodologies and extends to molecular electronics, nanofabrication, microscopy, chemical biology, photophysical characterization, UV-Vis-NIR spectroscopy, physical organic chemistry techniques, molecular imaging, and cell & animal studies depending on each project’s needs.
