3D bioprinting is recognized as the
ultimate additive
biomanufacturing
technology in tissue engineering and regeneration, augmented with
intelligent bioinks and bioprinters to construct tissues or organs,
thereby eliminating the stipulation for artificial organs. For 3D
bioprinting of soft tissues, such as kidneys, hearts, and other human
body parts, formulations of bioink with enhanced bioinspired rheological
and mechanical properties were essential. Nanomaterials-based hybrid
bioinks have the potential to overcome the above-mentioned problem
and require much attention among researchers. Natural and synthetic
nanomaterials such as carbon nanotubes, graphene oxides, titanium
oxides, nanosilicates, nanoclay, nanocellulose, etc. and their blended
have been used in various 3D bioprinters as bioinks and benefitted
enhanced bioprintability, biocompatibility, and biodegradability.
A limited number of articles were published, and the above-mentioned
requirement pushed us to write this review. We reviewed, explored,
and discussed the nanomaterials and nanocomposite-based hybrid bioinks
for the 3D bioprinting technology, 3D bioprinters properties, natural,
synthetic, and nanomaterial-based hybrid bioinks, including applications
with challenges, limitations, ethical considerations, potential solution
for future perspective, and technological advancement of efficient
and cost-effective 3D bioprinting methods in tissue regeneration and
healthcare.
