Abstract

We describe a novel platform technology for both significantly enhancing and obtaining chemiluminescence signatures "on-demand", subsequently named Microwave-Triggered Metal-Enhanced Chemiluminescence. By combining the use of silver nanoparticles to plasmon enhance chemiluminescence with the use of low power microwaves to localize heating around the nanostructures, we can both optically amplify and trigger chemiluminescence reactions. This approach is a significant advantage over traditional chemiluminescence techniques and methodologies, such as those used for Western Blots, which typically require long periods of time to collect chemiluminescence and offer few possibilities of optically amplifying the signatures.

摘要

我们描述了一种新型平台技术,该技术既能显著增强并“按需”获取化学发光信号,随后将其命名为微波触发金属增强化学发光。通过结合使用银纳米颗粒来等离子体增强化学发光以及使用低功率微波在纳米结构周围实现局部加热,我们既能实现光学放大又能触发化学发光反应。这种方法相对于传统化学发光技术和方法具有显著优势,例如用于蛋白质免疫印迹的那些技术,传统技术通常需要很长时间来收集化学发光信号,并且几乎没有光学放大信号的可能性。
