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
Inspired by the power generation mechanism of photofuel cell (PFC), a sensitive chloramphenicol (CAP) detection method was developed through the dual-photoelectrode photoelectrochemical (PEC) aptasensor. Assisted with the localized plasma resonance effect (LSPR) of AuNPs, the three-dimensional (3D) graphite carbon nitride (g-C 3 N 4 ) was acted as the photoanode to output high and stable photocurrent. The photocathode used porous metal organic framework (MOF) and Cu 2 O to form an N doped core-shell structure, which improved the aptasensor performance by co-participating in the photoresponse with the photoanode. The oxidation-reduction reaction together with the bias voltage of two electrodes completed a PFC system, which realized spontaneously power supply capability. In addition to the sensitivity, the selectivity, stability and repeatability of the as-fabricated device were also guaranteed, which was suitable for practical application. The novel PFC-based dual-photoelectrode PEC sensing system can be regarded as a potential method for antibiotics detection.
