Abstract
We study about the multi degrees of freedom control technology of floating type micro probe that is manipulated by the optical pressure. In this report, we discuss about the analysis method of viscous force and elastic force. The control model of the micro probe in nutrient medium is greatly affected by the fluid resistance. So, we construct the dynamical model that considers about the viscous force by the biological cells and the fluid force by the nutrient medium. And these forces are separately calculated from the measured vibration frequency and the measured amplitude. And we mention about the new function of the floating probe to dose the cell locally. To inject the medicine from the micro floating probe without contact, we apply the photo-acoustic effect that is induced by the nano-second pulse laser. This shock-induced elastic wave can form the droplet like the conventional ink jet printer.
