Abstract:
1. A method for manufacturing a substrate with surface structure by employing photothermal effect, comprising the steps of: providing a first substrate; distributing a plurality of nanoparticles on the provided first substrate, a particle size of each of the plurality of the nanoparticles being between 2.5 nm and 500 nm, a material of the nanoparticles being selected from a group consisting of Au, Cu, Ag and a combination thereof, said distributing including: irradiating the plurality of the nanoparticles on the provided first substrate with the specific wavelength, so that the irradiated nanoparticles convert irradiating energy to thermal energy, at least a part of the irradiated nanoparticles existing and maintaining in a form of a nanoparticle after being irradiated; forming a plurality of pores in a surface of the provided first substrate through the thermal energy, such that locations and shapes of the pores are at locations and have shapes of their respective irradiated nanoparticles; and after forming the pores, removing the irradiated nanoparticles in the form of the nanoparticle from the provided first substrate to obtain the first substrate with the pores formed, including:
