Carboxymethyldextran Sodium Salt is widely used in biomedical and pharmaceutical research due to its biocompatibility and water-soluble properties. It is commonly employed as a coating material for nanoparticles, enhancing their stability and preventing aggregation in biological environments. This chemical is also utilized in drug delivery systems, where it acts as a carrier to improve the solubility and bioavailability of hydrophobic drugs. Additionally, it serves as a matrix in tissue engineering, providing a supportive scaffold for cell growth and regeneration. In diagnostics, it is used in immunoassays to improve the sensitivity and specificity of detection methods. Its ability to form hydrogels makes it valuable in wound healing applications, where it helps maintain a moist environment and promotes tissue repair.
