MAGNETIC PARTICLE RETRIEVAL AND POSITIONING IN A MICROWELL ARRAY BY INTEGRATING OPTICAL TWEEZERS IN A DIGITAL MICROFLUIDIC PLATFORM

Abstract

© 14CBMS. This manuscript reports the manipulation of single magnetic microparticles confined in a microwell array by integrating optical tweezers in a digital microfluidic platform. In the presence of non-ionic surfactants the magnetic particles are trapped by a tightly focused laser. Once a particle is trapped in the laser beam it can be repositioned in a new microwell or released from the array and transported on the chip for further analysis.status: publishe
