Abstract :
There are many requirements to manipulate a droplet in the μTAS. A method of moving droplet by laser is proposed in this paper. A temperature gradient is generated in droplet by photo-thermal effect. It makes the Marangoni convection for driving force. It is succeeded to move droplet back and forth direction, which is combination of different solvent and solute.
