Immobilization of Hemoglobin at the Galleries of Layered Lepidocrocite-Related Potassium Lithium Titanate
The exfoliated nanosheets from the layered potassium lithium titanate K0.8Ti1.73Li0.27O4 can be assembled with the hemoglobin through the electrostatic attraction under mild conditions. The immobilized enzyme has regularly layered structure based on the small angel X-ray diffraction. The preparation method is low cost and the maximum bounding capacity of enzyme is large. The enzyme activity study showed that the immobilized Hb retained enzyme-like peroxidase activity, and the activity increased alongwith the increase of the interlayer distances. Michaelis-Menten model methods were used to study the peroxidase activity.
