Application scenarios: 1.Applications in anti-fouling, anti-corrosion, and self-cleaning, 2.Applications in anti-adhesion and resistance reduction, 3.Applications in microfluidic control, 4.Biochips.

1) Preliminary research basis and results

(1) Preparation of superhydrophobic surface

(2) Precisely control the adhesion (contact angle) of the material surface to the liquid

(3) Control liquid shape

(4) Control spontaneous movement of liquid

2) Research plan and expected results

The transformation of achievements achieved by relying on the above technologies is mainly reflected in:

(1) In terms of microfluidics and biochips, for example, on a superhydrophobic substrate, the surface components are modified by laser lithography, and the laser-processed area is converted into a superhydrophilic area. The biochip produced by this method can capture cells and fix them in patterned areas, which can realize cell screening and patterning. It can also be used for molecular diagnosis and protein and antibody fixation. It has good applications in the field of biological sciences. Laser direct writing technology can also be used for surface and interface processing of bioplastic substrates, glass substrates, electronic components, silicon-based materials, human implant materials, etc.

(2) Self-cleaning surface, anti-corrosion surface.
