Title:
SUBSTRATE, MICROFLUIDIC DEVICE, DRIVING METHOD AND MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2022/134062
Kind Code:
A1
Abstract:
A substrate for a microfluidic device, a microfluidic device, a driving method for a microfluidic device, and a method for manufacturing a substrate for a microfluidic device. A first substrate (102) comprises a first electrode layer (183) located on a first base (180), the first electrode layer (183) comprising a plurality of driving electrodes (170). The plurality of driving electrodes (170) defines at least one flow channel (128, 121, 132, 142, 154, 162) and at least one functional zone (112, 120, 130, 140, 150, 160) in the first substrate (102), the at least one functional zone (112, 120, 130, 140, 150 and 160) comprises a reagent zone (112), and the reagent zone (112) comprises a reagent zone liquid storage portion (204) and a droplet shape changing portion (205). The droplet shape changing portion (205) is adjacent to a reagent zone flow channel (206), and the reagent zone liquid storage portion (204) is located at the side of the droplet shape changing portion (205) away from the reagent zone flow channel (206). The reagent zone liquid storage portion (204), the droplet shape changing portion (205) and the reagent zone flow channel (206) are configured to generate an intermediate droplet covering the droplet shape changing portion (205) from the reagent zone liquid storage portion (204), and are configured to change the shape of the intermediate droplet so as to generate a reagent droplet in the reagent zone flow channel (206).
