Nanoscale Optoelectronics

Website: http://eecs.vanderbilt.edu/people/yaqiongxu/

In the Xu group we study electrical and optical properties of carbon-based nanoscale materials such as carbon nanotubes and graphene. We are particularly interested in the organic-inorganic interfaces of nanobiohybrid materials. Recently, we have developed an optoelectronic probing system to investigate the molecular couping between carbon nanotubes / graphene and biomolecules through electrical (scanning photocurrent microscope), optical (fluorescence microscope), and mechanical (dual-trap optical tweezers) measurements. We also explore the biomedical applications of these nanobiohybrids from drug delivery, molecular imaging, to biosensors.
