Bacterial cellulose-based three-dimensional carbon nanofibers for the sensitive and selective determination of uric acid

• In recent years, the interest in the optimization of novel nanomaterials for electrodes preparation has received tremendous attention. This article describe about develop an electrochemical sensor for to detect the uric acid (UA). Firstly, the sensing materials of carbon nanofibers (CNFs) were prepared through an economical approach under freeze-dried, mainly for CNFs were successfully synthesized through carbonized biomass green bacterial cellulose (BC) at 800 degrees C. The obtained CNFs were used to modify the glassy carbon electrode (GCE), and have an excellent electrochemical response towards the UA. Under the optimized condition, the current response of UA at the CNFs/GCE increased also the peak current linearly with the UA concentration, the limitation of detection (LOD) calculated as 0.29 mu M (S/N = 3), revealing the a high sensitivity and an broader analytical range of the as-prepared CNFs/GCE. Finally, the proposed electrochemical sensor can be used for detection of UA in human urine with the satisfactory result.
