Lasers and Nanophotonics

Lasers and nanophotonics have been essential tools in our laboratory's research. The femtosecond laser system in the lab is being used to probe, interrogate, and modify biological systems and provide new strategies for disease diagnosis and therapeutics. It is also a central component for our 3D nanoscale bioprinting apparatus. By integrating plasmonics with the laser systems, we can generate and manipulate light at the nanoscale, creating new applications in sensing, imaging, and gene regulation of biological systems. Novel cellular and molecular imaging techniques are essential to the advancement of fundamental biological research, as well as applied biomedical diagnostics.
