Abstract: Development of a reliable tool to detect hydrogen peroxide (H 2 O 2 ) and rutin in food-derived products and bioactive flavonoids is essential for food safety. Nevertheless, food/drug-based real samples are complex matrices that affect the sensor's specificity and sensitivity. For this purpose, we developed a simple electrochemical detection platform using covalent organic framework‑silver nanoparticles (COF-AgNPs). Based on spectral and electrochemical tests, COF-AgNPs displayed enhanced electroactive sites and facile electron transfer . For H 2 O 2 and rutin , the designed sensor surface exhibited outstanding concentration linearity of 0.5 nM–1000 μM and 1 nM–900 μM, respectively, along with superior detection limits of 0.126 nM and 0.133 nM. Additionally, it demonstrated acceptable reproducibility and interference capability. In practical analysis, H 2 O 2 and rutin were detected in milk, fruits, and drug samples with high recovery rates of 94.60–99.31 % ( n = 3). Consequently, the designed sensor is ideal for screening targets for H 2 O 2 and rutin in food sources and for food research.
