Recently, the Fujian Provincial Science and Technology Program project titled "Novel Paper-Based Surface-Enhanced Raman Scattering (SERS) Chips for Rapid Screening and Detection of Common Organophosphorus Pesticides in Tea", undertaken by FQII, successfully passed the acceptance evaluation by an expert panel.

    High-performance hydrogel SERS chips were developed and SERS sensors for organophosphorus pesticides were further constructed in the project. Sensing systems for chlorpyrifos, triazophos and methyl parathion were established, achieving high-throughput screening and detection of organophosphorus pesticides in tea. To date, 9 papers related to the project have been published in international scientific journals, and two Chinese invention patents have been filed for its core technologies. The research outcomes demonstrate significant social benefits and practical application value.
