Laser-assisted bioprinting is one among several technologies that are being developed in the recent and growing field of bioprinting. Bioprinting is defined as the use of computer-aided transfer processes for patterning and assembling living and non-living materials with a prescribed 2D or 3D organization in order to produce bio-engineered structures serving in regenerative medicine, pharmacology, and basic cell biology studies. We describe the physical parameters that need to be tuned for laser-assisted bioprinting of materials and cells, with high throughput and controlled printing resolution. We present its applications for printing cells and tissue-relevant biomaterials, both in vitro and in vivo. Finally, we discuss how this technique may help in reproducing the local cell micro-environment and dealing with tissue complexity and heterogeneity for fabricating functional tissue-engineered 3D constructs.
