在这封信中,我们报告了一种新的信号放大现象,迅速和显着增加的幅度和横向范围的原始信号。这种现象利用固定在导电表面上的酶在远离酶活性的原始位点的位置处产生放大的信号。在微流控平台上使用辣根过氧化物酶(HRP)和3,3 ',5,5'-四甲基联苯胺(TMB)的已建立的沉淀酶-底物系统在表面等离子体共振(SPR)成像系统上证明了该结果。
In this letter, we report a novel signal amplification phenomenon that rapidly and dramatically increases both the magnitude and the lateral extent of the original signal. This phenomenon utilizes an enzyme immobilized on a conductive surface to generate amplified signals at locations remote from the original site of enzyme activity. The result is demonstrated on a microfluidic platform using the established precipitating enzyme−substrate system of horseradish peroxidase (HRP) and 3,3‘,5,5‘-tetramethylbenzidine (TMB) on a surface plasmon resonance (SPR) imaging system.
