Sound waves transport droplets for rewritable lab-on-a-chip devices

Engineers at Duke University have demonstrated a versatile microfluidic lab-on-a-chip that uses sound waves to create tunnels in oil to digitally manipulate and transport droplets. The technology could form the basis of a small-scale, programmable, rewritable biomedical chip that is completely reusable for disparate purposes from on-site diagnostics to laboratory-based research.
