Control for Induced flows on gene combination with laser irradiation

讨论了激光捕获技术在水中激光操纵固体颗粒和DNA中的应用。可以画出以下几点。用几何光学理论估算的激光捕获力与激光器的出射功率成正比，并与激光捕获的无量纲化效率有关。通过估算激光穿过介质颗粒的偏转角，估算了激光对二氧化硅、玻璃和多孔道固体颗粒的捕获效率。调Q脉冲激光的捕获力大于连续激光的捕获力。结果表明，操纵力与峰值激光功率有关，而与平均激光功率无关。通过电流扫描仪，可以操纵多个固体颗粒进行运输。用激光照射揭示了水中的诱导流动。

Applications of laser trapping techniques for solid particles and DNA are discussed on laser manipulation in water. The following points can be drawn. The laser trapping force evaluated by the geometric optical theory is in proportion to the ejected power from a laser generator and moreover dependent to non-dimensional efficiency for laser trapping. The laser trapping efficiencies for silica, glass and polythchlane solid particles are estimated by evaluating deflection angles of laser beam passing through the particles from medium. The laser trapping force by a pulsed laser beam with Q-switch is greater than the force by a continuous laser beam. The force for the manipulation is revealed to be dependent on a peak laser power but not dependent on an average laser power. By Galvano scanner, multi solid particles can be manipulated for transportation. The induced flows in water are revealed with laser irradiation.
