Non-enzymatic electrochemical sensor for the simultaneous determination of adenosine, adenine and uric acid in whole blood and urine

An Analytical Method Based on Electrochemical Sensor for the Assessment of Insect Infestation in Flour

“…In addition, the oxidation potential of uric acid was influenced by pH as well. As the pH increased, the oxidation potential of uric acid also underwent a negative shift due to the involvement of protons in the electrochemical reaction [ 33 ]. Although a lower potential for electrochemical sensing helps detection, we finally chose pH 7 as the electrolyte environment for sensor operation considering the oxidation potential overlapping of some other substances, such as ascorbic acid [ 34 ].…”

Hexagonal cobalt oxide nanosheet-based enzymeless electrochemical uric acid sensor with improved sensitivity

“…Overall, the constructed sensing platform exhibited ultra-sensitivity, a good linear range and LOD, which were comparatively better than those found in previous reports (Table 1). 8,9,18,19,[34][35][36][37][38][39][40] This can be ascribed to the advanced sensing of UA using hexagonal cobalt oxide nanosheets.…”

Determination of ofloxacin in the presence of dopamine, paracetamol, and caffeine using a glassy carbon electrode based on carbon nanomaterials and gold nanoparticles

“…3,[5][6][7] However, electrochemical processes are more sensitive and cheaper, besides having good repeatability and short-time analyses, than the cited methods. [8][9][10] Despite the signicant number of electrochemical studies for FQ derivatives, there are no studies to date for detecting OFL in the presence of PAR, DOP, and CAF in effluents or human urine (synthetic) samples. Thus, developing an efficient electrochemical method for the detection and quantication of OFL in the presence of PAR, DOP, and CAF (interferents) is of fundamental importance.…”
