Abstract

In this study, we describe the confinement and two-dimensional (2-D) manipulation of single micro- and nanoscale particles in free solution using an integrated microfluidic device. The trapping mechanism is based solely on fluid flow, whereby individual particles are confined at the stagnation point of an extensional flow created at the junction of two perpendicular microchannels. Particle confinement and manipulation is performed by active and independent control of the stagnation point position along orthogonal directions in the microchannel junction using two integrated membrane valves. This new technique enables particle trapping and micromanipulation without the use of electrical, magnetic, optical and acoustic force fields.
