| Abstract: | In this paper,an optimized Nd:YAG UV Laser Microbeam System is introduced as a method in gene transfer.We use mice macrophages and Hela cells as experiment materials,and several fluorescence substance as transients,systematically studied the relationship of laser irradiation dose with cell viability and rate of foreign substance transfer.These results will be useful for further study on the mechanism of laser mierobeam interaction with cells. |
