【摘要】：无机/有机纳米杂化材料作为一种具有许多优异性能的新型材料,在传感器和生物芯片上得到了广泛的研究和应用。本论文分别采用自组装法制备四种磷酸锰基纳米花杂化材料,在对其各种性能充分研究的基础上,对其作为催化剂材料和传感器敏感膜材料的应用进行了详细研究。首先,采用自组装法制备出Mn3(PO4)2@BSA纳米花杂化材料。同时,采用化学沉积的方法在纳米花杂化材料表面沉积Pt纳米颗粒形成催化甲醇用催化剂。分别采用傅里叶红外光谱仪、XRD、XPS、SEM和TEM等测试技术分析材料的化学结构及表面形貌进行考察。研究发现,采用自组装法制备的Mn3(PO4)2@BSA纳米花杂化材料直径为20nm左右的花瓣颗粒;而负载Pt纳米颗粒以后纳米花杂化材料的形貌没有发生改变。采用电化学工作站对其电化学催化性能进行测试发现,纳米花材料具有很高的催化甲醇的能力并且具有很高的抗中毒能力。在磷酸锰基纳米花杂化材料负载Pt颗粒催化甲醇应用外,本文又研究了材料在电化学生物传感器方面的应用。采用自组装法制备出Mn3(PO4)2@BSA@Au、Mn3(PO4)2@Ig G和Mn3(PO4)2@RACanti三种纳米花杂化材料。分别采用FTIR、XRD、和SEM等测试技术分析材料的化学结构及表面形貌进行考察。通过电化学分析技术分析制备Mn3(PO4)2@BSA@Au、Mn3(PO4)2@Ig G和Mn3(PO4)2@RACanti三种纳米花杂化材料检测莱克多巴胺的最低检测限分别为26、4.6、9.32 pg.m L-1。结果表明,自组装技术制备的磷酸锰基纳米花杂化材料不仅具有较高的生物相容性,还具有良好的电化学催化性能,为以后磷酸锰纳米花杂化材料的其他应用研究奠定了一定的实验基础。
[Abstract]:As a new material with many excellent properties, inorganic / organic nano-hybrid materials have been widely studied and applied in sensors and biochips. In this paper, four kinds of manganese phosphate nano-flower hybrid materials were prepared by self-assembly method, and their applications as catalyst materials and sensor sensitive membrane materials were studied in detail on the basis of the full study of their various properties. Firstly, Mn3 (PO4) 2@BSA nano-flower hybrid materials were prepared by self-assembly method. At the same time, Pt nanoparticles were deposited on the surface of nano-flower hybrid materials by chemical deposition method to form catalysts for catalytic methanol. The chemical structure and surface morphology of the materials were investigated by Fourier transform infrared spectroscopy (FTIR), XRD,XPS,SEM and TEM. It was found that the diameter of Mn3 (PO4) 2@BSA nano-flower hybrid material prepared by self-assembly method was about 20nm, but the morphology of nano-flower hybrid material was not changed after loading Pt nanoparticles. Electrochemical workstation was used to test its electrochemical catalytic performance. It was found that the nano-flower material had a high catalytic ability to methanol and a high ability to resist poisoning. In addition to the application of manganese phosphate based nano-flower hybrid material supported on Pt particles as catalyst for methanol, the application of the material in electrochemical biosensor was also studied in this paper. Three nano-flower hybrid materials, Mn3 (PO4) 2BSA @ Auban3 (PO4) 2@Ig G and Mn3 (PO4) 2@RACanti, were prepared by self-assembly method. The chemical structure and surface morphology of the materials were investigated by FTIR,XRD, and SEM. The lowest detection limits for ractopamine detection of Mn3 (PO4) 2BSA @ Auban3 (PO4) 2@Ig G and Mn3 (PO4) 2@RACanti were 264.69.32 pg.m L-1, respectively. The results show that the hybrid materials prepared by self-assembly technology not only have high biocompatibility, but also have good electrochemical catalytic performance. It will lay a certain experimental foundation for other application research of manganese phosphate nano-flower hybrid material in the future.
