Abstract

In this paper, we have reported a method for Raman spectroscopy enhancement based on microsphere array chips. As an ideal and easily integrated optical microlens, dielectric microspheres have the advantages of small size and easy integration. In addition, the array of dielectric microspheres can accomplish high-density, high-throughput multi-detection mode, and its unique PNJ (photogenic nano-jet) effect can make the focusing intensity greatly improved, which can enhance the intensity of Raman spectrum in a limited way. The experimental results have shown that the microsphere array chip has significantly enhanced the detection sensitivity of liquid samples, with an enhancement factor of nearly 3.5 times and a relative standard deviation of only 7.760%. It can be seen that this method has the advantages of simple structure, wide application range and non-contact, which can effectively improve the detection sensitivity of liquid Raman spectroscopy.
