Abstract

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 μm × 5 μm × 4 μm, and step-by-step titration by precise reagent injection per two hundred thousand (2.0 × 10-5) in volume of the micro chamber (157 nanoliter: 1 mm in diameter 7times 200 μm in height).
