Examples

• Immobilization of a-chymotripsin in isopropylacrylamide – hydroxyethylmethacrylate copolymer gel : a-chymotripsin was immobilized by physical entrapment within copolymer gels. The kinetic studies for the system show that the overall reaction rate is controlled by substrate diffusion in gel matrix. (Source : H. Cicek, A. Tuncel, "Immobilization of a-chymotrypsin in thermally reversible isopropylacrylamide-hydroxyethylmethacrylate copolymer gel", Journal of Polymer Science Part A: Polymer Chemistry, Volume 36, Issue 4, 1998)

• Platinum-Catalyzed Enzyme Electrodes Immobilized on Gold Using Self-Assembled Layers : Biosensors are produced by immobilizing an enzyme (glucose oxidase) on gold surface through bonding to self assembled monolayers of alkanethiols. The biosensor showed good sensitivity to glucose and a large dynamic range. (Source : J. J. Gooding, V. G. Praig, and E. A. H. Hall, "Platinum-Catalyzed Enzyme Electrodes Immobilized on Gold Using Self-Assembled Layers", Analytical Chemistry, 70(11), 2396-2402)
