“…Previously, various techniques have been employed to determine the uric acid concentration such as gas chromatography-mass spectrometry 8 , high-performance liquid chromatography [9][10] , UV-Vis spectrophotometry 11 , chemiluminescence 12 , fluorescence. 13 However, these methods are reported complex to perform, time consuming, laborious, and requires expensive equipment thus impractical for daily analysis. Among these techniques, electrochemical method has offered an alternative approach for uric acid determination due to its simplicity, rapid detection, low cost, and need only a less amount of sample for routine analysis.…”

A glassy carbon electrode modified with electrochemically reduced graphene oxide (ErGO) and poly (3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) was developed for the uric acid determination with dopamine as interference in artificial saliva. The electrochemical performance of the fabricated electrode was studied using both techniques of cyclic voltammetry (CV) and differential pulse voltammetry (DPV), under optimized conditions. Using DPV, the sensor based on ErGO/PEDOT:PSS modified GCE displayed a linear relationship in the concentration ranges of 10-100 µM for uric acid. This uric acid sensor exhibited a high sensitivity with the detection limits of 1.08 µM and the quantitation limit of 3.61 µM. This sensor also showed good reproducibility for uric acid detection in the artificial saliva in 5 consecutive days measurements. This device was successfully used to analyze uric acid in the artificial saliva as well as in human saliva sample using standard addition method.

“…16 The signicance of dopamine and uric acid in the clinical diagnostic perspectives has drawn great awareness for the development of sensitive and reliable techniques for their detection. Over the past decade, various analytical techniques have been established including liquid chromatography, 17,18 capillary electrophoresis, 19 uorescence spectroscopy, 20,21 colorimetry, 22,23 UV-Vis spectrophotometry 24 and electrochemical analysis. 25,26 Due to the electroactive nature of DA and UA, electrochemical techniques are of high interest because they offer certain benets such as cost effectiveness, rapid response, high sensitivity, simple instrumentation and eld portability.…”

“…1 Therefore, it becomes imperative to monitor UA levels regularly. The commonly used methods to detect UA in clinic include high performance liquid chromatography (HPLC), 6 spectrophotometry 7 chemiluminescence analysis, enzyme electrode analysis, uric acid biosensor, 8,9 and so on. Among them, uric acid biosensor has been paid more and more attention because of its advantages of simple manufacture, low cost, high sensitivity and good selectivity.…”

A uric acid (UA) electrochemical biosensor was constructed using ferrocene (fc) decorated cuprous oxide (cu 2 o) enhanced electro-active characteristics and covalently immobilized with uricase (Uox) on glassy carbon electrode (Gce). the electrochemical characteristics of the fabricated electrode was analysed by cyclic voltammetry, electrochemical impedance spectroscopy and differential pulse voltammetry (DpV). DpV studies revealed rapid response of fabricated electrode Uox/fc/cu 2 o/Gce towards UA in a wide concentration range of 0.1-1,000 μM with a sensitivity of 1.900 μA mM −1 cm −2 and very low detection limit of 0.0596 μM. A very low magnitude Michaelis-Menten constant (Km) value was evaluated as 34.7351 μM which indicated the chemical attraction of the enzyme towards the UA was much higher. the developed biosensor was successfully applied to detect UA in human urine samples. Moreover, reproducibility and stability studies demonstrated the fabricated UOx/Fc/ cu 2 O/GCE biosensor had high reproducibility with a RSD of 2.8% and good reusability with a RSD of 3.2%. Specificity studies results showed the fabricated biosensor had strong anti-interference ability. the improved sensor performance was attributed to the synergistic electronic properties of cu 2 o and fc that provided enhances delectrocatalytic activity and electron transfer. the present biosensor can be extended for use in clinical settings.
