Laser-Based Bioprinting

Abstract

As one of the earliest technologies in patterning living cells, laser-based bioprinting (LBB) has been a powerful technique thanks to its high resolution and precision in bioprinting of high-cell density tissue constructs. Despite its great capabilities in fabrication of high-fidelity tissue constructs, LBB has little use in bioprinting domain compared to other bioprinting modalities due to its complex and costly laser-involved setup and a limited ability to generate heterocellular three-dimensional thick constructs. This chapter presents the evolution of LBB technology and describes its modalities in detail under two major groups including processes involving photopolymerization (stereolithography, dynamic optical ...
