dc.description.abstract The introduction of nanoparticles to intact plant cells is promising as a transporting technique of a wide range of functional molecules. Among various molecular delivery methods, femtosecond laser photoinjection possesses target selectivity at a single cell level and is potentially applicable for many types of materials. However, for plant cells, the vacuoles’ turgor pressure and the thick cell wall limit the application of photoinjection to only small objects. In this work, we overcome these limitations by employing a single pulse irradiation from a femtosecond laser amplifier. After laser irradiation on intact tobacco BY-2 cells, 80 nm fluorescent nanoparticles dispersed in a cell culture medium were successfully injected into their cytoplasm. This breakthrough would lead to a vast utilization of nanoparticles containing functional molecules for single cell manipulation in plant physiological study and genetic engineering. Such an injection was observed even when the laser pulse was focused neither on the cell wall nor on the cell membrane, but beside the cells. With these results, we suggest pore formation on the cell membrane by instantaneous deformation induced by an intense femtosecond laser pulse as an injection mechanism of nanoparticles. Reported photomechanical effects of the amplified femtosecond laser on the permeability of the biological membrane would offer new perspectives in biophotonics. ja
