Abstract
A one-inlet and nine outlet multi sorting system using thermoreversible gelation of polymer (Mebiol Gel/spl trade/) was developed for efficient particle and biomolecule handling. The system uses 3/spl times/3 arrayed microchannels which have 9 cross points. One outlet out of nine is selected and the flow pass is determined by IR irradiation to the certain junctions and channels where gel areas are formed. The IR irradiation points are selected using a PC controlled digital mirror device (DMD). Since nine flow passes are formed by the IR beams reflected by the DMD, nine outlets sorting are performed in simple microchannels without any mechanical valve systems. Switching time of less than 60 msec is obtained in this system.
