SUTD scientists led development of novel acoustofluidic technology that isolates submicron particles

SUTD researchers and their collaborators developed a novel nanoacoustic trapping device that manipulates particles within submicron ranges by applying a structured elastic layer at the interface between a microfluidic channel and a travelling surface acoustic wave (SAW). This novel acoustofluidic device provides a promising solution for sorting and size-selective capture of nanoscale objects that requires patterning into discrete traps at the single-particle level.
