About the Project
A typical lab-on-chip (LOC) device consists of sensing element, control and signal processing, and microfluidic components for bio-sample preparations and chemical reactions. Acoustic waves have unique advantages for LOC device because they can be used for both sensing and microfluidic actuation. Acoustofluidics can handle liquid volumes from picolitres to tens of microlitres for mixing, pumping, jetting and nebulisation, and can also manipulate particles/cells/bacteria inside the microchannels. In this PhD project, we will explore generation of various modes of acoustic waves using piezoelectric materials and advanced thin films on various substrates, and will study thing film based wave mode generations, and then apply these wave modes together with nanomaterials and nanostructures for microfluidic functions and bio-detection. The research will also be focused on interaction of biological cells and bacteria in the liquid with acoustic waves, aiming for wide potential applications in bacteria treatment, drug delivery, cell manipulation, antibiotic resistance and gene analysis. Effects of various designs of electrodes or interdigital transducers and microfluidics properties as well as usages of microchamber and microchannels will be investigated. The work includes both experimental and simulation/theoretical studies of acoustic wave generations and identification of wave modes as well as wave/cell interactions.
