Research Overview

Research in the Li laboratory is in the interdisciplinary field of nanoscience and nanotechnology, with an emphasis on the development of novel applications of micro-/nano- devices in chemical/biochemical analysis, biomedicine, energy conversion and storage, environmental monitoring and protection, and electronics. Our foci are the fundamental understanding of new phenomena involved in nanomaterials growth/assembly, characterization, surface modification, and device fabrication/evaluation. The projects involve close collaboration with partners from academia, industry, and government labs. Current projects include: (a)Nanomaterials growth: mainly focused on high-aspect ratio nanofibers including carbon nanotubes (CNTs), carbon nanofibers (CNFs), semiconducting inorganic crystalline nanowires, and core-shell nanowires; (b)Biosensor development: mainly focused on embedded nanoelectrode arrays based on vertically aligned CNFs for electrochemical detection of proteases activity and nanoscale dielectrophoretic capture and detection of  virus and bacteria; (c) Energy conversion and storage: mainly focused on developing a 3D architecture based on vertical core-shell nanowire arrays for dye-sensitized solar cells, lithium-ion battery, and supercapacitors.
