MCM-41固载牛血清白蛋白复合材料的制备、表征及发光
Preparation, Characterization and Luminescence of MCM-41 Immobilized Bovine Serum Albumin Composite Material
摘要
Abstract
In this research, nanoscale MCM-41 molecular sieve was prepared using hydrothermal method and then bovine serum albumin (BSA) was immobilized in the above host to prepare ( MCM-41 )-BSA composite materials by physical adsorption method. Chemical analysis showed that BSA had entered into the above-stated host material and its immobilization amount was 55. 68 mg (BSA)/g (MCM-41). Powder X-ray diffraction (XRD) results indicated that crystallinity degree of composite materials was maintained good and basic frameworks of the molecular sieve were preserved intact and were not destructed due to BSA introduction. The low temperature N2 adsorption-desorption study results at 77 K showed that BSA had already partially entered in the molecular sieve pore channels. The measurement results by scanning electron microscopy (SEM) displayed that the diameter of ( MCM-41) -BSA sample was 100 ± 10 nm. The luminescence study showed that in the (MCM-41)-BSA sample the conformation of BSA was not changed.关键词
