In this field, single-molecule Raman spectroscopy imaging technology has been widely used to characterize the structure and dynamics of single molecules. However, due to the limitations of the optical diffraction limit, traditional single-molecule Raman spectroscopy imaging technology can only be characterized in the sub-micron spatial resolution range. To overcome this limitation, plasma-enhanced technology has been introduced into the field of single-molecule Raman spectroscopy imaging.In this paper, a new plasma-enhanced single-molecule Raman spectroscopy imaging technology is proposed, which can characterize the structure and dynamics of single molecules in the sub-nanometer spatial resolution range. Specifically, we will use gold nanorod plasmon resonance to 精品文档---下载后可任意编辑improve the signal-to-noise ratio...
