Ferrites are effectively used in electrochemical uric acid (UA) sensing applications. Herein, we synthesised cobalt ferrite (CoFe 2 O 4 ) nanoparticles by one step solution combustion method. The prepared CoFe was coated on nickel foam (NF) substrate to fabricate the electrode and tested using phosphate buffer saline (PBS). small crystallite size of 14 nm as well large area active sites 0.139 cm contributed towards enhanced sensitivity 0.735 mA.mM −1 −2 . limit detection (LOD) @NF sensor is 26.24 μM. UA occurs an adsorption-controlled kinetics electrostatic interaction at a pH ∼7.2 where anion negatively charge while surface positively charged it displays quasi-reversible reaction. Additionally, repeatability, selectivity, reproducibility were investigated. real-time application validated spot-urine, commercial milk Barracuda fish samples, which show recovery percentage between 99.5% 101.8%. shelf-life observed be 28 days. Hence, this highly sensitive can for clinical diagnosis hyperuricemia food safety purposes.
