Abstract

See full text

An integrated microfluidic device and its usage are provided. The microfluidic device comprises an upper layer (1) and a lower layer (2), wherein the lower layer (2) is bound to the upper layer (1). The upper layer (1) comprises a micro-channel (3) and the lower layer (2) comprises a micro-well (7) array. The micro-channel (3) is in fluidic connection with the micro-well (7) array, and the height of the micro-channel (3) is greater than the diameter of the oocyte (4) flowing through the micro-channel (3). The integrated microfluidic device has many advantages including low cost, high integration, and convenient operation, and has application prospects in reproductive medicine and the research of fertilization and embryo early development.
