Fabrication of an Electrocatalyst Based on Rare Earth Manganites Incorporated with Carbon Nanofiber Hybrids: An Efficient Electrochemical Biosensor for the Detection of Anti-Inflammatory Drug Mefenamic Acid

Pharmaceutical and personal care products are emerging as a new category of environmental pollution. Analytical drug detection from biological sample for is still crucial today. Mefenamic acid (MA) an anti-inflammatory utilized its antipyretic analgesic properties, which harmful to patients at higher dosages also recognized chemical pollutant that harms the environment. In this view, Dysprosium manganite/carbon nanofiber (DMO/CNF) was prepared by hydrothermal method electrochemical MA. DMO/CNF/GCE exhibits high selectivity, excellent anti-interference, good stability, reproducibility toward The enhanced performance attributed their synergetic interaction. Under optimized conditions, shows wide linear range 0.01–741 μM low LOD 0.009 μM. Satisfactory recoveries were obtained human blood tablet samples. Thus, proposed DMO/CNF nanocomposite emerges promising material
