Caffeine is a very important ingredient for preserving the nutritional quality of foods. But, when ingested in excess, it responsible numerous health problems, hence analysis caffeine drinks and food products pivotal. This study employed g-C3N4/ZnO nanocomposite (NC) to analyze coffee soft drinks. Scanning electron microscopy (SEM), Fourier transform infrared (FTIR), X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET) were structural characterization. oxidation was successfully accomplished by modifying glassy carbon electrodes (GCEs) with NC. The sensitivity detection using g-C3N4/ZnO/GCE noticeably improved because its better electrocatalytic activity. sensor showed good analytical performances like selectivity, inter-electrode reproducibility, stability. It also responded wide range concentrations between 1 1000 µM. estimated limit (LOD) quantification (LOQ) found be 0.063 µM 0.211 µM, respectively. content real samples has been effectively determined recovery values 91.41–103.84 %.

In this work, a molecularly imprinted polymer (MIP)-based photoelectrochemical (PEC) sensor for the detection of ciprofloxacin (CIP) was constructed. Carbon-modified ZnO (ZnO/C) nanocomposite with adjustable zinc content prepared by carbonaceous method, facilitating visible light absorption and electron transition. The structure, morphology, surface chemistry ZnO/C were well characterized. MIP membrane formed electropolymerizing, nanocomposite, o-phenylenediamine (C6H4(NH3)2,o-PD), CIP as highly efficient photoactive materials, functional monomer, template, respectively. PEC properties different electrodes measured analyzed. MIP-based showed excellent sensitivity selectivity towards CIP, displaying broad linear range from 0.01 nM to 1000 nM, low limit 8.41 pM, satisfied recovery rates within 96.8%103.2%. exhibited reliable reproducibility stability, relative standard deviation (RSD) 2.48% in milk. constructed not only provides powerful route but also can be extended detect other antibiotics food natural environment.
