RETRACTED: Development of carbon paste electrodes modified by molecularly imprinted polymer as potentiometry sensor of uric acid

A novel non-enzymatic electrochemical uric acid sensing method based on nanohydroxyapatite from eggshell biowaste immobilized on a zinc oxide nanoparticle modified activated carbon electrode (Hap-Esb/ZnONPs/ACE)

“…87,88 Whereas the decrease of UA peak current response in the presence of glucose might be due to the competition between glucose and UA to fill the cavity of Hap-Esb. 16,23,25,87,89 We also noticed that the presence of tyrosine increased the peak current response. 25 Given that the difference of peak current responses are less than 10% (between 1–9.15%), our proposed sensor shows a remarkably selectivity.…”

“…This result indicated that the modification of the size of carbon paste was effective in increasing the electroconductivity of GOx/MCPE. In this research, a carbon paste electrode modified with nanofiber-polyaniline was used as the working electrodes because they are easily changed, inexpensive, and easily regenerated 15 . Maximum current was 5.39 mA (carbon paste size of 3x3 mm 2 ), which was better than that reported in our previous studies.…”
