2.Shenzhen Topology Precision Film Technology Co., Ltd. is specialized in Industry and agriculture,Machinery and industry equipment,Industry-specific equipment supply since established in 10 years ago.So far,our company has established its branch companies in major cities throughout the country.Formed in 4th Floor, Building 1, Tingwei Industrial Park, No. 6 Liufang Road, Xin'an Street, Bao'an District, Shenzhen, China,Bao'an District,Shenzhen City,Guangdong Province,China as the center, the radiation sales system and service network.Details:4.SERS technology, like the infrared spectrum, belongs to the molecular vibrational spectrum and can reflect the characteristic structure of the molecule. However, the Raman scattering effect is a very weak process, and generally its intensity is only about 10^-10 of the incident light intensity. Therefore, the Raman signal is very weak, and it is almost necessary to use some kind of enhancement effect to conduct Raman spectroscopy on surface-adsorbed species.SERS technology is the first high-quality SERS technology obtained by Fleischmann et al. after roughening the surface of smooth silver electrodes in 1974 to adsorb monolayer pyridine molecules on the surface of silver electrodes. Van Duyne and his collaborators then found through experiments and calculations that the Raman scattering signal of each pyridine molecule adsorbed on the rough silver surface is about 6 orders of magnitude stronger than the Raman scattering signal of pyridine in the solution phase. It is pointed out that this is a surface enhancement effect related to rough surfaces, which is called Surface-enhanced Raman spectroscopy (SERS) effect.
