Description
Halloysite clay nanotubes have been introduced to form functional composites with a variety of biomedical applications.This research enhances the catalytic activity of enzymes by encasing them in within the nanoscale tube. The loading efficiency and biocatalytic activity of urease and glucose Oxidase were measured by UV-Vis spectrophotometry, thermogravimetric analysis, and bioactivity assays. It was possible to immobilize enzymes on the external surface or in the inner lumen of halloysite. 50% of these proteins remain immobilized in the tubes lumens while another 50% was slowly released. The immobilized enzymes retain their activity for an extended period of time and at elevated temperatures.
