A chip-to-chip nanoliter microfluidic dispenser.

A high-throughput microfluidic device is developed to handle liquid dispensation in nanoliter range. The dispenser system shows no cross-contamination between the microwells, indicating its great potential in large-scale screening experiments. An array of 115 nl PCR reactions, as well as the single channel addressable chip demonstrate the high flexibility and wide applications of this novel system.
