研究了10,10 ′-二甲基-9,9 ′-联吖啶二硝酸盐(光泽精)-过氧化氢-N-甲基吖啶酮化学发光体系在不同类型的膜模拟剂和均相溶剂中的特性,考察了不同类型的膜模拟剂对光泽精-过氧化氢光反应的影响。表面活性剂十六烷基三甲基氯化铵、3-(N-十二烷基-N,N-二甲基铵基)丙烷-1-磺酸盐、聚氧乙烯(23)十二烷醇、双十八烷基二甲基溴化铵和α-、β-和γ-环糊精的水溶液使CL强度分别增强3.4、2.5、4、1.6、2.3、14和12.6倍。在所有阴离子表面活性剂介质的存在下,观察到CL排放的降低。简要描述了影响CL增强或减少的幅度的各种实验变量,并讨论了这些药剂作为CL增强剂的优点和局限性。CL强度的改变是合理的,这些不同的膜模拟剂的反应速率和/或激发效率的影响。最后,分析的影响和使用这种膜模拟剂光泽精荧光分析的可能优势进行了讨论。
The 10,10′-dimethyl-9,9′-biacridinium dinitrate (lucigenin)-hydrogen peroxide-N-methylacridone chemiluminescence (CL) system was characterised in different types of membrane mimetic agents and homogeneous solvents, and the effects of various membrane mimetic agents on the lucigenin-hydrogen peroxide light reaction were assessed. Aqueous solutions of the surfactants hexadecyltrimethylammonium chloride, 3-(N-dodecyl-N,N-dimethylammonio)propane-1-sulphonate, polyoxyethylene(23)dodecanol, dioctadecyldimethylammonium bromide and α-, β- and γ-cyclodextrin enhanced the CL intensity by factors of up to 3.4, 2.5, 4, 1.6, 2.3, 14 and 12.6, respectively. A lowering of the CL emission was observed in the presence of all anionic surfactant media examined. The various experimental variables that influence the magnitude of the CL enhancements or reductions are briefly described, and the advantages and limitations of these agents as CL enhancers are discussed. The alterations in the CL intensity are rationalised in terms of the effect of these different membrane mimetic agents on the rate of the reaction and/or excitation efficiency. Lastly, the analytical implications and possible advantages of using such membrane mimetic agents in lucigenin chemiluminescent assays are discussed.
