| Popis: | Acoustofluidics has been increasingly applied in biology, medicine and chemistry due to its versatility in manipulating fluids, cells and nano-/micro-particles. Reducing cost and time for manufacturing surface acoustic wave (SAW)-based acoustofluidic devices could facilitate rapid applications of the SAW technology and attract more researchers into this field. We present herein a novel but simple technology to form a cost-effective SAW device by stacking electrodes made from printed circuit board (PCB) and piezoelectric substrate to generate acoustic waves. PCB-based SAW devices (PCB-SAW) have been characterized and compared to the conventional SAW devices made using the cleanroom fabrication processes. The PCB-SAW devices were successfully used to manipulate microparticles within droplets and microchannels, which showed similar performance with those previously achieved using the standard SAW devices. The PCB-SAW was further used as an acoustic tweezer to precisely pattern the human lung cancer cells inside the microchannel. Cell viability tests proved that the PCB-SAW possessed good biocompatibility to be potentially applied as a cost-effective and precise tool for acoustophoresis and beyond. |
