coupled graphene oxide with provskite nanomaterials as potential electrochemical modifier agent for precise detection of morin within kiwi samples

Abstract: flavonoids are considered to be natural antioxidants found in plants that have anti-viral, anti-inflammatory, anti-mutagenic, anti-carcinogenic and anti-stress activities. morin is an important phytochemical pentahydroxyflavone that contains a wide range of polyphenol compounds, mainly found in fruits, vegetables, and some chinese herbs, due to its potential applications in the food, pharmaceutical, and cosmetic sectors. have attracted a lot of attention.in the present study, perovskite / graphene oxide nanosheets were used to modify the surface of a glassy carbon electrode to identify and measure the morphine composition in a true kiwifruit sample. to ensure the accuracy of the synthesis of the desired nanosheets, the structure and particle size of the mentioned compound and the modified electrode were examined by various identification techniques including sem, xrd, ft-ir, eds. the electrochemical behavior of morin on the surface of the carbon glass electrode of the above modified glass was investigated using cyclic voltammetry techniques. a difference with a linear range of 10 to 110μm and a detection limit of 4.49μm was obtained. the results obtained from the sensor designed for maureen measurement indicate appropriate parsing characteristics including low detection limits, wide linear range and good performance for maureen measurement. also, in order to check the accuracy, the recovery values of 97.5 indicate the high performance of the sensor designed in real samples. stability, reproducibility and high reproducibility of the modified electrode are other prominent features of the designed sensor.
