Abstract:
Particle separation in passive micro fluidic channels has been investigated in straight channels with contracting and expanding geometry is studied. The angles in the entrance of contacting part of the channel are varied and the influence of the forces on the particle focusing is studied at various fluid flow rates. Single focusing position could be achieved for a certain flow rate and an angle of inclination at the entrance of a contracting part in the direction of flow.
