This technology is a rapid food safety screening SERS chip with high sensitivity, stability, uniformity, and reproducibility. It addresses the current market gap for a reliable SERS chip solution. In food safety applications, it has achieved LOD for melamine down to 0.05 ppm, bisphenol A down to 1 ppb, and methylene blue (MB) down to 1x10^-10 M, both below regulatory standards. Additionally, it can detect preservatives, antibiotics, and natural food. The technology has also been patented and recognized in academic journals.

This technology’s breakthrough is the development of a novel, highly sensitive, cost-effective, and reliable SERS screening chip, along with three new SERS mechanisms. Compared to traditional SERS substrates, this technology maintains stability without significant signal decay and remains anti-oxidizing for six months. This innovation greatly enhances the practicality and applicability of SERS substrates, presenting a significant breakthrough solution for high-throughput food safety testing.

This technology boasts high sensitivity, high stability (resisting oxidation for up to six months), and low cost, making it highly commercially competitive. It can be used to test for fungicides, melamine, preservatives, bisphenol A, and antibiotics. Additionally, 500 units have been transferred to Örebro University in Sweden, demonstrating its significant industrial applicability.
