Application of Different Spectral Methods for Target Analysis

Abstract

Spectral analysis methods are widely used for the analysis of different targets such as viruses, bacteria, heavy metals and their harmful substances due to their simplicity and efficiency. Among these spectral analysis methods, the study of luminescence and light absorption of different substances has important theoretical and practical significance. Atoms are different and emit different bright-line spectra, and the atoms of each element have a certain bright-line spectrum. Therefore, a diverse of different spectroscopic techniques can be used to achieve various target detection. In this research, four common spectral analysis methods are introduced, including Raman spectroscopic analysis, electroluminescence analysis, fluorescence analysis and colorimetric analysis. And this research analyzes the detection effect of these four spectral analysis methods on different targets, such as virus and pathogens. With the features of scientific type spectroscopic instruments or systems with high sensitivity, high resolution, high reliability and multidimensional information in spectroscopic techniques, the developed spectroscopic techniques to detect viruses effectively. And the demand for its application will be more urgent and will surely become a direction of great interest for quite a long time to come.
