Research Interests
-
My research focuses on the creation of novel laser surgery and imaging technologies with high precision. In my group, we achieve this goal by exploiting the nonlinear interaction between femtosecond laser pulses and tissue as a precise ablation tool for surgery as well as a three-dimensional probing tool for imaging. We further improve the capabilities of these tools by using the nanoscale focusing power of plasmonic gold nanoparticles.
We aim at advancing both biological sciences and clinical practice. To advance biological sciences, for example, we develop novel microfluidic devices for high throughout nanosurgery. To improve clinical practice, for example, we engineer new microsurgery instrumentation. Our research problems range from understanding the biological mechanisms of nerve regeneration and degeneration after injury in model organisms to developing novel non-invasive optical tools for treatment and diagnosis of cancer.
- Femtosecond laser microsurgery: Optical-scissors applicable at the sub-cellular and cellular level with application to nerve regeneration and cancer treatment. We perform both experimental and theoretical research to elucidate the fundamentals of fs-laser interaction with tissue and the physical processes involved during ablation (such as laser-induced cavitation bubble dynamics, extent of the laser-induced photo-damage, plasma shielding during surgery with low NA-lenses, laser-induced heating of gold nanoparticles in tissue, etc.).
- High-throughput microfluidic devices for studying nerve regeneration and degeneration: Development of new microfluidic devices for studying the dynamic processes involved in nerve regeneration and degeneration of C. elegans and for enabling automated high throughput genetic and pharmacological screenings.
- Miniaturized handheld probes for fs-laser microsurgery: Development of miniaturized endoscopic probes for fs-laser microsurgery guided by two-photon imaging, utilizing optical MEMS scanning mirrors and photonic crystal fibers.
- Plasmonic laser nanosurgery using molecularly targeted gold nanoparticles: Fundamental study of laser nanoablation of biological materials based on laser-field enhancement near gold nanoparticles. The delivery of nanoparticles to biomarkers of interest allows for the removal of tissue in large areas using single laser pulses while ablation localized near nanoparticles improves the precision of the surgery at the nanoscopic levels.
- Two-photon luminescence imaging using molecularly targeted gold nanorods: Development of a new multi-photon imaging modality using the bright luminescence properties of gold nanorods to increase imaging depth of highly scattered tissue for early cancer detection. We found that two photon luminescence of gold nanorod labeled cells is 3000 times brighter than the autofluorescence of unlabelled cells.
