Study of “acoustic tweezer” chip for particles driving
1 Nanjing University of Science and Technology, Nanjing 210094
Surface Acoustic Wave (SAW) is one of the sound waves that travel parallel to the surface of an elastic material, and is capable of manipulating microparticles. This SAW device was named acoustic tweezers. Acoustic tweezers possess advantages of energy-efficiency, small size and easy-to-produce. Herein, we developed an acoustic tweezer chip to sort microparticles of different sizes. The chip consists of a pair of interdigital transducer (IDT) and a PDMS microfluidic channel. The IDTs generate the surface acoustic wave which acts on the particles in the microchannel. Finally the sorting of particles can be seen.
Key words: manipulating microparticles / acoustic tweezer / low energy consumption / interdigital transducer
