In this study, we present a novel approach using amperometric microsensors to detect quercetin in cosmetic formulations and track its metabolic behavior after topical application. This method offers sensitive, real-time alternative conventional techniques, enabling the detection of quercetin’s bioavailability, transformation into active metabolites, potential therapeutic effects when applied skin. Quercetin (Q) is bioactive flavonoid known for potent antioxidant properties, naturally numerous plants, particularly those with applications formulations. response growing interest developing plant-based dermo-cosmetic solutions, study investigates electrochemical quercetin, ketone-type flavonoid, extracted from Gingko biloba essential oil. Three newly designed were developed assess their efficacy detecting botanical samples. The sensor configurations utilized two forms carbon material as foundation: graphite (G) nanoparticles (CNs). These base materials modified paraffin oil, chitosan (CHIT), cobalt(II) tetraphenylporphyrin (Co(II)TPP) enhance sensitivity. Differential pulse voltammetry (DPV) served analytical investigation. Among sensors, CHIT/G–CN microsensor exhibited highest sensitivity, limit 1.22 × 10−7 mol L−1, followed by G–CN (5.64 10−8 L−1) Co(II)TPP/G–CN (9.80 microsensors. minimum detectable concentration was observed CoP/G–CN microsensors, achieving threshold low 0.0001 μmol L−1. Recovery rates relative standard deviation (RSD) values averaged 97.4% ± 0.43, underscoring sensors’ reliability matrices.
