電界誘起気泡圧壊による皮膚への低侵襲インジェクション技術へ向けた基礎研究

抄録

For the present study, evaluation of collateral damage area and quantity of injected reagent was carried out for the electrically induced bubble injector (needle-free injector) which was invented in our laboratory. It was confirmed that the input power is closely related to the depth of the injection area. The speed of the propagation of a bubble just before the cavitation phenomena is also closely related to the input power and scale of cavitation. The perforation depth has been achieved 100～500μm for the applied voltage of 900～1500V. This study will contribute to minimally-invasive injection to skin in the bio-medical field.
