From: Femtosecond laser treatment enhances DNA transfection efficiency in vivo
Schematic diagram depicting the femtosecond laser setup for treatment of mice. The laser beam was transmitted through a focal lens to allow tuning of laser power density by varying target distance from the focal lens. The beam was transmitted through a small 0.5 cm diameter hole in a wooden block to allow for optimal alignment of the laser beam with the DNA injection site on the mice.
