AI Technical Summary
Existing digital microfluidic chips are difficult to achieve high-throughput droplet manipulation and precise manipulation of tiny substances within microdroplets on the same chip, and photoelectric tweezers chips are easily damaged and have high operating voltage requirements.
A novel digital microfluidic chip was designed, which separates the photoelectric tweezers functional area from the digital microfluidic functional area through an isolation structure. A hydrophobic layer is set in the photoelectric tweezers functional area, and the chip is manipulated by combining dielectric wetting force and photoelectrophoresis force to avoid photoconductive layer breakdown.
This enables high-throughput parallel operation of microdroplets and fine manipulation of tiny substances within microdroplets on the same chip, improving chip durability and operational efficiency.
