The effects of water-soluble polymers(WSPs), such as bovine serum albumin(BSA) and polyethylenimine(PEI), on chemiluminescence(CL) in an aqueous solution have been studied. The CL emission, particularly in the initial stage of the CL reaction, was strongly enhanced by increasing the concentrations of these WSPs. This was attributed to the acceleration of the chemical reactions prior to the formation of the light-emitting species. BSA was also peculiar in that it could enhance CL under neutral pH conditions. It was suggested that these WSPs offered hydrophobic and basic microenvironments well suited to the CL reaction.
水溶性聚合物(WSPs),如牛血清白蛋白(BSA)和聚乙烯亚胺(PEI),对水溶液中化学发光(CL)的影响已被研究。这些WSPs浓度的增加强烈增强了CL发射,特别是在CL反应的初始阶段。这归因于在发光物种形成之前的化学反应加速。BSA的特殊之处在于,它可以在中性pH条件下增强CL。据推测,这些WSPs提供了适合CL反应的疏水和碱性微环境。
