Detection of uric acid (UA) is a foremost area of research as abnormal increases in its level can be used to diagnose diseases such as gout, renal disorders, and arthritis. Development of efficient test diagnostics to detect UA in human urine is therefore required. In this study, magnesium oxide was prepared via a hydrothermal route. X-ray diffraction analysis revealed formation of amorphous cubic MgO. The transverse optical phonon mode of cubic MgO was confirmed at the zone center at ~ 479 cm−1. Emission peaks observed at 362 nm, 383 nm, 495 nm, and 521 nm showed the high-quality luminescent behavior of the undoped MgO. Scanning electron microscopy images confirmed formation of MgO microflowers. Cyclic voltammetry results confirmed the excellent electrocatalytic ability of Ni/Co-codoped MgO nanostructures. Chronoamperometry (CA) results confirmed that the synthesized Ni/Co-codoped MgO nanostructure possessed good stability under UA. Such transition-metal element-codoped MgO microflowers with improved performance could be suitable as an excellent tool for clinical diagnostics.
