Abstract
Injection and delivery of small amount reagent in aqueous solution for cell chip was performed utilizing regeneratively amplified femtosecond laser system. In our new trial, the reagent integrated on a solid strip are released and delivered to targeted cells with the femutosecond laser-induced impulsive-force. The reagent was fixed in poly(vinyl alcohol) or polystyrene film on a glass-substrate strip. When a single pulsed femtosecond laser was focused in the solution, the film near the focal point was fragmented and the reagent was dispersed in 45-μm φ area at 50 μm from the surface of the reagent strip. As examples cardiomyocyte beating cells of P19CL6 were bombed with epinephrine and acetylcholine, and as a result the beating ratio of the cells were quickly stimulated and suppressed, respectively. The results demonstrate that the present method is a promising key nano/micro technology for diagnosis and drug discovery.
