We propose a high-throughput picoliter droplet generation system which can generate different volume of droplets continuously. Using a cascade multi-stage separation channel and droplet dispersion pillars, various volume ratio between the separated droplets is realized only by changing the flow rate. Uniform picoliter droplets are generated about 1000 droplets/sec in the cascade multi-stage separation...
Precise titration using sub-picoliter droplet injection microfluidic system is proposed. This system can to measure less than 1 picoliter of reagent and to deliver to the micro chamber without diffusion which becomes major concern when the reagent volume is smaller. A prototype device can generate a droplet of 0.8 picoliter (800 femtoliter) in the metering channel of 40 mum times 5 mum times 4 mum,...
