| Outline of Final Research Achievements |
Laser induced shock wave (LISW) is used for gene transfer into cells. LISW is a shock wave because its propagation velocity is higher than the sound speed. A proposed device structure can generate high pulsed electric field due to piezoelectricity when LISW propagates in this structure. We consider that this pulsed electric field is also effective on gene transfection. In this study, we clarified the experimental conditions of pulsed electric field generation by LISW irradiation, and experimentally showed the shock wave formation in the confined structure using 0.05 mm-thick black rubber target even when the laser fluence is as low as 0.4 J/cm2. We also investigated the transfection efficiency of FITC dextran to several cell species when an LISW generated by thin black rubber target (0.07 mm in thickness) was irradiated to their cells, and clarified the experimental conditions in order to improve the transfection efficiency.
