3D Bioprinting of Advanced Bioinks for Tissue Regeneration and Biosensor Development

Three-dimensional (3D) bioprinting technology has become a unique system for tissue regeneration and biosensor development by controlled deposition of bioinks to produce complex constructs. Different bioprinters including laser-assisted and extrusion-based have been introduced and used to produce constructs with high resolution, cell viability and shape fidelity for tissue development. In addition, microfluidic technology, organ-on-a-chip and electrospinning technology are used to produce biosensing products to diagnose and monitor living systems. One of the most critical materials used for bioprinting is bioink. Several bioinks of an advanced level and different compositions have been developed too. Here, we briefly highlighted the characteristics, advantages, and disadvantages of some bioprinters and advanced bioinks that have been developed recently. We also stated some tissue engineering applications with the use of 3D bioprinting. Lastly, we mentioned a few key areas for main focus in the future.
