摘要: The aim of tissue engineering is to produce functional three-dimensional (3D) substitutes. Regarding native organ and complexity, cell density spatial 3D organization, which influence behavior fate, are key parameters in engineering. Laser-Assisted Bioprinting (LAB) allows one print cells liquid materials with a cell- or picoliter-level resolution. Thus, LAB seems be an emerging promising technology fabricate tissue-like structures that have the physiological functionality their counterparts. This has additional advantages such as automation, reproducibility, high throughput. It makes compatible (industrial) fabrication constructs physiologically relevant sizes. Here we present exhaustively numerous steps allow printing viable well-preserved micrometer pattern. To facilitate understanding whole patterning experiment using LAB, it discussed two parts: (1) preprocessing: laser set-up, bio-ink cartridge bio-paper preparation, pattern design; (2) processing: on bio-paper.
