Application

Application Comment Organism
synthesis the addition of ferrous ions (Fe2+) induces the formation of hydroxyl radicals from the hydrogen peroxide, which act as initiating species for the microgel synthesis. Poly(N-vinyl)caprolactam (PVCL) microgels are synthesized by precipitation polymerization initiated by the enzyme and a conventional azo-initiator 2,2'-azobis(N-(2-carboxyethyl)-2-methylpropionamidine) tetrahydrate. The use of enzymes in precipitation polymerization leads to the encapsulation of enzymes in formed microgels. After the GOx-induced polymerization and purification of the microgels, high enzyme activity could be determined in the microgels, enabling facile synthesis of core-shell microgels. The glucose oxidase-based initiator system is a powerful and promising alternative to azo- or peroxide-initiated polymerization, leading to the formation of polymers at low synthesis temperatures Aspergillus niger
