Description
Summary:This work aimed at showing the interest of the composite material based on layered double hydroxides （LDHs） and chitosan （CHT） as suitable host matrix likely to immobilize enzyme onto electrode surface for amperometric biosensing application. This hybrid material combined the advantages of inorganic LDHs and organic biopolymer, CHT. Thus, the developments of cholesterol biosensor were achieved by both electrooxidation and electroreduction of the enzymatic-generated hydrogen peroxide based on cholesterol oxidase （ChOx） and horseradish oeroxidase （HRP）.
