Tintbionic® CHIMA

CHIMA is a methacrylated derivative of chitosan. The precursor of CHIMA is chitosan, the second most common natural polysaccharide after cellulose, composed of deacetylated parts (beta-[1,4]-d-glucosamine) and acetylated parts (N-acetyl-d-glucosamine), obtained through the partial deacetylation of chitin. It has found wide application in the construction of products as a scaffold that promotes cell adhesion. Methacrylation allows for rapid and stable crosslinking of the material under UV/Vis light in the presence of a photoinitiator such as LAP. CHIMA can be used as a mixture with other methacrylates. The degree of methacrylation is determined based on 1H NMR analysis.
