Laser ablation patterning by interference induces directional cell growth.

Laser-patterning by interference is a method to introduce micropatterns on the surface of TXL and TXB, which were shown to have an effect on the L929 growth. In this experiment, we have produced collagen-coated and laser-patterned TXL and TXB with different dimensions; the groove width of the line patterns varied approximately from 1.2 microm to 9.
