Lasers are becoming increasingly popular for numerous medical applications. The use of femtosecond laser pulses is particularly attractive for such applications thanks to the “cold” process of tissue ablation which is confined only to the focal volume of the laser beam. In our group we use femtosecond pulses of various wavelength to excite specifically targeted noble-metal nanoparticles at their plasmonic resonance. The combined effect of the short pulses and small particles allows for specific manipulations of cells and tissue with minimal toxicity and collateral damage.
