摘要
磁性纳米材料因具有特殊的量子尺寸效应、小尺寸效应、表面效应、宏观量子隧道效应,所以在磁学、生物学、光学、方面有着广泛的应用,具有广阔的应用前景。本论文采用溶剂热法制备了盐酸多巴胺修饰的四氧化三铁磁性纳米粒子,后用戊二醛共价偶联后进行了固定化乙酰胆碱酯酶的应用研究。对合成的磁性纳米粒子以及其表面改性后的产物进行了透射电镜、红外光谱测定、XRD表征、磁性能分析,对其结构及性能进行了表征及分析。
Due to its special quantum size effect, small size effect, surface effect, macroscopic quantum tun-neling effect, magnetic nanoparticles have been widely used in magnetics, biology, optics, with broad application prospects. The ferroferric oxide magnetic nanoparticles modified by dopamine hydrochloride were prepared using solvothermal method, and then the application research of immobilizing acetylcholinesterase after covalent attachment of glutaraldehyde was carried out. The structure and property of the synthetic magnetic nanoparticles and modified products were characterized and analyzed using transmission electron microscope, infrared spectrometry, XRD characterization and magnetic property.
