摘要: Potassium ions play pivotal roles in biological systems. A simple and effective Raman scattering-based protocol for the detection of physiological potassium level human serum has been developed. We employed sodium cobaltinitrite, which can react with to form potassium-sodium cobaltinitrite. Combining hydrophobic surface scattering detection, highly reproducible spectra cobaltinitrite be obtained sensitivity. The characteristic peak was used distinguish it from other kinds matter, its intensity monitor amounts serum. Because contribution aggregation Raman, this great potential practical extended measuring use by spectrum method.
