Assessing the robust growth and lipid-accumulating characteristics of Scenedesmus sp. for biodiesel production

Abstract

3D bioprinting is an upcoming technique to fabricate tissues and organs through periodic arrangement of various biological materials, including biochemicals and biocells, in a precisely controlled manner. 3D bioprinting has gained momentum in the generation of 3D functional human constructs mimicking native tissues/organs. Various biomaterials based on carbohydrates, proteins, and nucleic acids along with nanocomposites are being used to develop biocompatible and biodegradable scaffolds promoting cell adhesion and proliferation in the tissues engineered using 3D printing. Apart from being biocompatible, polysaccharides are economical and renewable and thus are being explored for the formation of bioinks in regenerative medicine. Extracellular matrix proteins and other structural proteins are known for their impact on tissue mechanics as well as cell behavior. They have the capability to empower scaffold fabrication with high mechanical strength and porosity and provide cellular mimicry. DNA-based hydrogels and scaffold materials with self-assembling and hybridization properties are ideal for 3D bioprinting. This chapter deals with the principles and applications of 3D bioprinting approach employing the complex biopolymers and nanomaterials and their composites involved in fabrication/regeneration of tissues and organs. © 2019 Elsevier Inc.
