C ell patterning commonly employs photolithographic methods for the micro-fabrication of structures on silicon chip. This requires expensive photo-mask development and complex photolithographic processing. Laser based patterning for cell printing has been previously employed a low cost option to avoid such processing steps. Separate to this, laser ablation of polymers is an active area of research promising high aspect ratios. This seminar reports the first application of laser ablation as a means of ablating the biocompatible polymer parylene-C from SiO2 substrates for the patterning of human brain cells, hence, removing the expensive photolithographic steps. The results demonstrate how this method provides a low cost, rapid prototyping option and high cell yield solution.
