title = "Micro-swimmer trap-and-release using standing surface acoustic waves",
abstract = "Manipulation of cells using standing surface acoustic waves (SSAW) is useful in many biomedical applications; however, trapping of highly-motile micro-swimmers like Chlamydomonas reinhardtii (CR) is challenging using traditional SSAW devices incorporating elastomeric microchannels. In these devices, generation of the required high trapping force heats samples beyond the thermotolerance threshold of the cells leading to loss of function or death. Herein, we demonstrate trap-and-release of CR using SSAW devices with wet-etched glass channels driven at ~10 and ~25 MHz. Infrared thermography confirms a reduction in operating temperature for glass (versus polydimethylsiloxane, PDMS) channels to achieve sufficient trapping force with improved biocompatibility.",
