Three-dimensional (3D) bioprinting technology allows the production of porous structures with complex and varied geometries, which facilitates development equally dispersed cells orderly release signal components. This is in contrast to traditional methods used produce tissue scaffolding. To date, 3D has employed a range cell-laden materials, including organic synthetic polymers, construct scaffolding systems manufacture extracellular matrix (ECM). Still, there are several challenges meeting technical issues bio-ink formulations, such as printability bio-inks, customization mechanical biological properties bio-implants, guidance cell activities biomaterials, etc. The main objective this article discuss various strategies for preparing bio-inks mimic native tissue's environment. A discussion also been conducted about process parameters formulations printing, structure requirements, fabrication durable bio-scaffolds. present study reviews 3D-printing techniques. Conclusively, potential paths smart bioink/scaffolds have outlined regeneration.

Nowadays, as a result of the frequent occurrence accidental injuries and traumas such bone damage, number people causing or fractures is increasing around world. The design fabrication ideal tissue engineering (BTE) materials have become research hotspot in scientific community, thus provide novel path for treatment diseases. Among used to construct scaffolds BTE, including metals, bioceramics, bioglasses, biomacromolecules, synthetic organic polymers, etc., natural biopolymers more advantages against them because they can interact with cells well, polymers be widely studied applied field BTE. In particular, alginate has excellent biocompatibility, good biodegradability, non-immunogenicity, non-toxicity, wide sources, low price, easy gelation, enabling itself biomaterial. However, pure hydrogel BTE scaffold material still many shortcomings, insufficient mechanical properties, disintegration physiological environments, lack cell-specific recognition sites, which severely limits its clinical application order overcome defects single hydrogels, researchers prepared composite hydrogels by adding one matrix certain proportion improve their bioapplicability. For this reason, review will introduce detail methods constructing alginate/polymer alginate/bioprotein polypeptide alginate/bioceramic alginate/nanoclay well biological trends materials, look forward future direction. These exhibit both unexceptionable biochemical high value repair regeneration, providing theoretical basis development sustainable alginate-based functional biomedical materials.

The increasing demand of advanced biomedical materials for bone repair and regeneration has spurred significant research in recent years. While traditional hydrogels offer promising biocompatibility easy fabrication, their application reconstruction is often impeded by inadequate structural integrity biological functions. Graphene oxide (GO) emerged as a transformative additive, renowned its exceptional mechanical chemical properties, well ability to enhance the hydrogels. In this study, incorporation GO into chitosan (CS) investigated, achieving bioinspired with enhanced strength stability, which are crucial supporting regeneration. Additionally, self‐assembled synthetic peptide nanofibers (PNFs) employed facilitate biomimetic mineralization hydrogels, critical process effective remodeling. This innovative composite hydrogel not only achieves but also exhibits osteogenic, pro‐angiogenic, antioxidant properties essential repair. novel method takes advantage distinctive GO, PNFs, biomass providing robust material solution potential significantly advance field tissue engineering.

Phase change materials (PCMs) are that exhibit thermal response characteristics, allowing them to be utilized in the biological field for precise and controllable temperature regulation. Due considerations of biosafety spatial limitations within human tissue, amount PCMs used medical applications is relatively small. Therefore, researchers often augment with various enhance their performance increase practical value. The dispersion nanoparticles modify thermophysical properties has emerged as a mature concept. This paper aims elucidate role nanomaterials addressing deficiencies enhancing PCMs. Specifically, it discusses methods stabilization mechanisms PCMs, well effects on such conductivity, latent heat, specific heat capacity. Furthermore, explores how nano-additives contribute improved conductivity underlying enhanced heat. Additionally, potential biomedical fields proposed. Finally, this provides comprehensive analysis offers suggestions future research maximize utilization applications.
