Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Background: In the present work, an electrochemical sensor for detection of paracetamol was fabricated by modifying a glassy carbon electrode (GCE) using multiwalled carbon nanotube (MWCNT) decorated with bismuth oxide (BiO) based on using the drop dry technique. Methods: The prepared composite electrode was characterized by scanning electron microscopy–energy dispersive X-ray spectroscopy (SEM–EDS), Fourier transform infrared spectroscopy (FT-IR), and cyclic voltammetry (CV). Electrochemical techniques such as cyclic voltammetry, chronoamperometry, and square wave voltammetry (SWV) were used to study the behavior of paracetamol. Results: The modification process improved the redox kinetics of paracetamol as shown by increased peak currents. The peak current varied linearly with increment of paracetamol concentration in the range of 0.02 to 28 μM with a sensitivity of 1.133 μA μM. A detection limit of 0.0052 μM was obtained. Conclusion: The proposed method was successfully applied to determination of paracetamol in biological samples with recoveries in the range 94.3–98.7%.
