“…Alkaline solutions combined with enzymes are found to produce higher yields for collagen extraction. Tang et al used alkaline protease to further cross-link pure collagen fibers obtained from alkaline-pretreated bovine hides, which were then woven into material [71]. Alkaline pretreatment can also contribute to maintaining structural integrity and preventing ASC loss.…”

“…The evolutionary mechanism of bovine collagen hiding conformation in Na 2 S solution was clarified, whereby its capacity for hydrolysis follows the order NaOH < NaHS < Na 2 S under the same conditions. Researchers further developed a green, high-efficiency processing approach for isolating collagen fiber bundles after pre-swelling bovine hides [71], which was comparable to conventional NaOH preswelling in reducing pollutant load. Specifically, treated pollutant loads result in 58%, 76.75%, 76.03%, and 61.07% reduction in chemical oxygen demand, ammonia nitrogen, total solids, and discharged wastewater, respectively.…”

Collagen with a multi-hierarchical architecture exhibits powerful biological performance, thus being developed in biomedical applications as a processing building block. The isolated collagen after extraction from biological tissues can be processed into various forms such as fibrils, scaffolds, membranes, microspheres, hydrogels, and sponges for further use in specific applications. This review briefly discusses the multi-hierarchical structure, powerful biological performances, extraction, and processing approaches of collagen as a natural biomaterial. The processing of collagen including dissolution, self-assembly, cross-linking, and electrospinning, is discussed to show more feasibility for specific applications of collagen composite biomaterials. Further emphasis is directed towards the biomedical applications of drug and gene delivery, as well as tissue repair involving bone, cartilage, vascular, and corneal, along with wound healing. Additionally, there is a focus on the development of flexible sensors and electronic skins (e-skins). Furthermore, the potential challenges and perspectives for the development of collagen-based biomaterials are proposed. In short, collagen-based biomaterials are expected to facilitate sustainable development and the next generation of advanced biomaterial applications. Graphical Abstract
