Used in natural dyeing processes due to its ability to produce blue pigments when reacted with amino acids, particularly in traditional textiles and food colorants. Shows potential in crosslinking proteins and polysaccharides for biomedical applications such as tissue engineering and drug delivery systems. Exhibits anti-inflammatory and antioxidant properties, making it valuable in cosmetic formulations and skincare products. Investigated for use in improving the mechanical strength and biocompatibility of biodegradable hydrogels and scaffolds. Also explored for its role in enhancing the stability of protein-based materials without the toxicity associated with synthetic crosslinkers.
