Crosslinking is a chemical process where two or more polymer chains are linked together, forming a network. This enhances the material's strength, stability, and resistance to heat and chemicals. Crosslinking is commonly used in the production of materials like rubber and plastics, improving their durability and performance. In biological contexts, crosslinking can refer to the bonding of proteins or nucleic acids, which is essential for maintaining the structure and function of cells. For example, in the formation of collagen, crosslinking helps provide structural integrity to tissues, making it crucial for wound healing and overall tissue repair.
