Solid-state Electrochemiluminescence Study Based on Nanomaterial Modified Electrodes and Tri-color System

Abstract

自从联吡啶钌电致化学发光的现象(ECL)被发现以来,ECL的分析方法就引起了人们极大的兴趣。由于该方法具有检测背景低、灵敏度高、线性范围宽等特点,被广泛应用于常规分析检测、生化检测和环境监测的研究中。本论文在固相ECL研究的基础上,结合三原色原理,针对ECL研究中存在的问题提出了解决的方法。 本论文共五章。 第一章,文献综述,主要介绍ECL的基本原理及发展概况。 第二章,建立在电极表面修饰金纳米颗粒的方法,并研究了修饰过程中金纳米颗粒的生长机理。实验中,首先在玻碳电极上修饰了规整的金纳米颗粒,然后采用自组装技术,利用羧基和氨基的缩合反应,将发光试剂二(2,2’–二联吡啶)(5-氨基-1,...Since the first report of Tris(2,2’–bipyridyl) ruthenium(II) (Ru(bpy)32+) electrogenerated chemiluminescence (ECL), Ru(bpy)32+ ECL has been received great attention and applied in many fields including daily analysis, bioassay and environmental monitoring, due to its low back ground noise, high sensitivity and wide linear range. In this dissertation, the research works are focus on the resolution ...学位:理学博士院系专业:化学化工学院化学系_分析化学学号:1912005140305
