Absorption spectroscopy and selective ablation of lipids and proteins in vitro using a mid-infrared supercontinuum fiber laser

Using wavelengths between 2.6 and 3.8 microns from a fiber-based supercontinuum laser, lipids and proteins can be identified and selectively ablated. Absorption spectroscopy and selective ablation are conducted on atherosclerotic plaque constituents and adipose/fat tissues.
