Laser-Tissue Interactions Interactions of laser light with biological tissue vary with pulse
duration, intensity and wavelength of the radiation. They include
photo-chemical, thermal, mechanical and multi-photon phenomena. We study
mechanisms of interaction of pulsed lasers with biological cells and tissues
including Ø
Cellular and tissue hyperthermia (milliseconds to
seconds) Ø
Dynamics of tissue
coagulation (micro- to milliseconds). Ø
Multi-photon ionization in liquids (femto- to
picoseconds) Ø
Explosive vaporization and cavitation We develop applications of these interactions to: §
Minimally-traumatic
retinal therapy §
Targeted drug delivery §
Tissue dissection and ablation |
