尿液表面增强拉曼光谱的初步研究
The Preliminary Study of Urine by Surface Enhanced Raman Spectroscopy
摘要
Abstract
The absorption spectroscopy of silver colloids and the mixture of silver colloids with urine were measured.The urine' s Raman spectroscopy were tested and analyzed before and after the adding of silver colloids.Based on the technology of Surface Enhanced Raman Spectroscopy, the intensity of the urine' s Raman signal in the silver colloids was increased obviously and the SERS signal of uric acid in urine was successfully detected.The characteristic Raman bands of urine were tentatively assigned.The SERS of the urine of the morning and the night were compared and analyzed.The detection of morning urine bears higher credibility and SNR.The results showed that the surface-enhanced Raman spectroscopy might provide a new kind of method for the clinic detection of urine.关键词
