Research Projects

Dr. Yong-Qing Li studies the exciting field of biophotonics.  Work in the Li lab uses techniques including optical tweezers and Raman spectroscopy, live-cell light microscopy, Raman imaging and atomic force microscopy to understand fundamental biological process of single cells and cellular heterogeneity.  Projects include optical pulling of airborne particles and lifting of large objects by light, monitoring dynamic germination, outgrowth, and growth of single bacterial spores in nutrients and high pressure environment, and label-free surface enhanced Raman spectroscopy (SERS) for Ras proteins-based cancer diagnose and therapy. There are both graduate- and undergraduate-level projects in the lab.
