Manufacturing of substrates with different surface roughness for cell migration test by two-photon polymerization method
Abstract(#br)In this paper, cell substrates with different assigned surface roughness are manufactured by two-photon polymerization (TPP) method. The surface roughness of substrate can be controlled by changing the laser power, voxel distance, and scan line gap of the 3D printing process in TPP system. The micro substrate structure manufactured by TPP will be used as a master sample for reproducing multiple replica samples by nanoimprint lithography (NIL).
