表面增强拉曼光谱（SERS）中的静电力引导分子
Guiding molecules with electrostatic forces in Surface Enhanced Raman Spectroscopy (SERS)
摘要：
在表面增强拉曼散射（SERS）中，将分子吸引到表面等离子体共振增强将产生信号的地方的问题是最基本的问题之一，也是该效应的每一个应用的最初障碍。我们探讨了利用静电力作为一种手段，“引导”带电分子在溶液中对SERS活性基板的可能性。我们还明确地表明，选择性地提高不同类型的染料，根据其电荷的可能性，我们简要地讨论了其他应用程序中的“静电指导”可能是一个选项可能的扩展。
英文摘要：
In Surface Enhanced Raman Scattering (SERS) the problem of drawing molecules to the places where surface plasmon resonance enhancements will produce signals is one of the most basic ones, and the initial obstacle to every application of the effect. We explore the possibility of using electrostatic forces as a means to "guide" charged molecules in solution toward SERS active substrates. We also show explicitly the possibility of selectively enhancing different types of dyes according to their charge, and we discuss briefly possible extensions for other applications where "electrostatic guiding" could be an option.
