碩士 / 國立成功大學 / 化學工程學系碩博士班 / 101 / Surface acoustic wave (SAW) is one of the techniques which can be applied to focus or separate microparticles in a microfluidic device. Through photolithography, the inter-digital transducer (IDT) is fabricated and integrated with microchannel. The alternating current electric field with appropriate frequency is applied and electric energy is transferred into mechanical energy owing to the converse piezoelectric effect. Pressure gradient is generated in the microchannel and the particles are focused or separated. The variables which will affect SAW such as particle size and output power are widely discussed and found in the literatures. In this study, the effect of the working frequency and compressibility of the medium is explored.
Microalgae are an important source for biomass energy. Due to their high growth rate and high lipid abundance, developing a strategy for high throughput detection of lipid inside microalgae is critical. In this study, we attempt to apply SSAW to focus the algal cells and study for feasibility of performing continuous detection of lipid content inside microalgae.
