Metric Options: Counts1 Year3 YearSelecting 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
In this study, we report a facile and sensitive amperometric determination of isoniazid (INZ) content in urine samples based on gallic acid induced reduced graphene oxide (GA-RGO) modified glassy carbon electrode. The GA-RGO composite was prepared by simple sonication method with the aid of gallic acid. The GA-RGO composite was characterized by field emission scanning electron microscope, Raman spectroscopy, and X-ray diffraction pattern. The electrochemical behavior of GA-RGO modified electrode was evaluated by cyclic voltammetry (CV) towards the oxidation of INZ. The GA-RGO modified electrode showed excellent electrocatalytic activity and lower potential detection towards the sensing of INZ. The electroanalytical sensing of INZ exhibited acceptable linear response ranges from 0.05 to 783.1 μM with the limit of detection (LOD) of 0.01 μM. The GA-RGO modified electrode displayed good storage stability, excellent reproducibility toward the sensing of INZ. Moreover, the GA-RGO modified electrode was successfully applied to the determination of INZ content in urine samples, showed satisfactory recovery values for practical applications.
