infrared laser (PIRL) has been developed by Dwayne Miller and his group [1]. By irradiating tissue with PIRL proteins
are transferred from the tissue into the gas phase within at aerosol plume without chan

chemical composition of the protein is maintained during tissue ablation via PIRL. In this study, the efficiency of tissue
homogenization performed with PIRL and with classical homogenization was investigated using
