Special Issue Information
Dear Colleagues,
Hydrogels receive a great amount of interest in scientific advancements and their applications in the areas of 3D bioprinting and tissue engineering, therapeutics, and cell delivery. Hydrogel materials for 3D bioprinting, bio-inks, and tissue engineering have been developed and commercialized to their specific applications in accordance with the advancement of information technology, such as the 3D printing industry and soft robots. Examples of 3D printing in tissue engineering are blood vessel, bone, skin, bladder, cartilage, meniscus, and many other complex organs and tissues. Both synthetic and natural polymers, including their hybrid forms with ceramics, nano–microparticles, and fibers have been employed in 3D forms with (stem) cells for tissue engineering. 3D hydrogels either contain cells (bio-inks) or do not contain cells for their applications in tissue engineering, and diverse cells could be employed for different tissues and organ regeneration.
Even though there has been significant development in functional hydrogels for 3D printing and tissue engineering, it is very important both to synthesize novel functional hydrogels and to control their properties during biomimetic printing of tissue/organ structures. Development of novel 3D printing hydrogels could help to obtain diverse synthetic and natural polymers. The required hydrogel properties could be biocompatibility, 3D printability, post-printing morphological stability, cell encapsulation/viability, and tissue regeneration of the hydrogels for the success of tissue/organ engineering.
This Special Issue on hydrogels for 3D bioprinting and (bio-ink) tissue engineering aims to cover all aspects of the aforementioned subjects, including, for instance, the synthesis and characterizations of novel 3D printing biomaterials, self-healing gels, self-assembling hydrogels, biomimetic gels, delivery of bioactive molecules in/from 3D printing gels, in vitro/in vivo tissue regeneration of hydrogels, control of hydrogels and processing for 3D (bio)printing, and applications of 3D bioprinting gels to diverse tissues and organs such as bone, cartilage, blood vessels, skin, and others in all the related fields mentioned in the keywords.
This Special Issue welcomes reports on recent findings and reviews from experts in this frontier sector.
