摘要:
A microfluidic device has a plurality of H-shaped micro channels not connected to each other and formed on a substrate. Each of the H-shaped micro channels comprises two main channels separately placed on two opposite sides in parallel and a plurality of sub-channels perpendicularly connected to the two main channels. The present invention is designed in such a way that various reagents dropped into different H-shaped micro channels are immobilized on respective sub-channels because of the different widths of the main channel and sub-channel. Afterwards the reagents are coated with a layer of polymer. The polymer has a porous structure that allows the passage of any sample to be tested. Finally, a plurality of upper channels parallel to one another are directly fabricated in the polymer, or in another layer of polymer stacked on the previous polymer.

The present invention discloses a method using a microfluidic chip to sort high motility sperm. In the present invention, sperm and a medium are respectively injected into a microchannel of a microfluidic chip via several inlets. Owing to the characteristic of microfluidics, the sperm and the medium form a sperm laminar flow and medium laminar flow in the microchannels; the sperm laminar flow and the medium laminar flow are parallel to each other. The higher motile sperm may pass through at least one laminar flow within a limited time, whereby different motility levels of sperm can be respectively collected from different outlets.

A fabrication method of three-dimensional microstructures is to fabricate a real 3D microstructure. First, a substrate is coated with an anti-reflection layer to absorb reflected exposure light, and then the anti-reflection layer is overlaid with a first thick photoresist. After having been fully exposed by a first photo mask, a predetermined exposure depth of the first thick photoresist is achieved by a second photo mask and dosage-controlled UV exposure. If the unexposed areas of the first thick photoresist are released during a development step, a single-layer microstructure is created. Inversely, a multi-layered microstructure can be obtained simply by repeating the process described above. After all layers are laminated on the substrate, all unexposed areas of the all thick photoresist layers are released and connected to each other during a development step.
