Christine Démoré (Dundee) and Agilent Technologies
Life scientists are making significant advances in the understanding of biological systems through their increasing ability to hold and reposition cells using non-contact tweezing. A range of techniques for this manipulation already exists, including optical tweezing and dielectrophoresis. Ultrasound can also be used, but advanced devices are a much newer topic, with the University of Dundee recently pioneering research into ultrasound transducer array-based tweezers. These offer a combination of electronic programmability, integration with control electronics, and larger forces, in the multiple nanonewton range. In turn, this will allow new applications in life sciences, for example to manipulate relatively large groups of cells together.
The aim of this INSPIRE studentship is to configure and test sonotweezer devices in flexible and innovative ways to develop understanding of ultrasound interaction with cells and to demonstrate accurate control over the forces and positioning.
The student will explore how the devices can be exploited to demonstrate the fundamental physics of sonotweezing and to validate the theoretically predicted forces on particles. Relevant applications include separation and sorting of cells, investigation of cell motility, measurements of cell forces, and tissue engineering; the focus of this project will be on cell motility in particular.
