Original abstract

This work revolves around preparation of microfluidic chip that can generate surface acoustic wave and standing surface acoustic wave with its own designed frequency. This wave is generated on lithium niobate by interdigital transducers placed directly on the substrate. Chip prepared this way was ready for its primary usage in particles flow manipulation and separation particles in flow by their size. Our pilot measurements included separation, sorting and trapping of polystyrene particles with diameter of 5 and 15 µm. Platform based on surface acoustic wave techniques could be used for biological fluid samples. This platform enables manipulation and study of cells, while preserving their structure, function and biological integrity. Thus, we also studied Trachydiscus minutus as a testing biological cell for trapping. Apart from separation, sorting and trapping, we have observed polystyrene particle accumulation in the field between uniform pair of IDTs.
