| Popis: | ABSTRACTIn bone tissue engineering, the search for improved repair methods is crucial, given the drawbacks of traditional strategies like donor site issues and immune rejection. Addressing these challenges, this paper introduces an innovative GelMA/Bentonite composite bioink for 3D bioprinting, designed to create scaffolds that closely emulate native bone tissue. GelMA is selected for its biocompatibility and modifiable mechanics, while Bentonite's mineral richness and ion exchange capacity are harnessed to enhance scaffold structure and promote an osteogenic microenvironment. This research marks the inaugural incorporation of Bentonite into a bioink, a significant stride forward given its established safety in pharmaceuticals and versatility across industries. This bioink formulation signifies a breakthrough in bone tissue engineering, aiming to improve the osteointegration and regeneration of bone tissue. Combining Bentonite with GelMA marks a key step in creating bioinks that enhance bone healing, potentially transforming scaffold-based bone regeneration and pioneering the use of natural nanomaterials in medicine. |
