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
Determination of pork DNA is essential to avoid the serious allergens imposed by it as well as for halal authentication for certain community. The needed sensor should be able to identify the pork DNA in rapid way and sensitive to ultra-low molarity detection. In this work we developed a surface enhanced Raman spectroscopy sensor (SERS) using silver nanoparticles (AgNPs) on Si matrix. A deep investigation of the effect of the laser wavelength on the sensing efficiency has been performed. Wavelength dependent sensing mechanisms are deliberately studied in the current research. Further the selectivity of sensor towards Pork DNA discrimination is exhibited with Chicken DNA analysis. The developed SERS sensor identifies the Pork DNA down to 13.6 fg/ μL proving its excellent sensitivity. The statistical outfit studies with regard to the developed sensor shows the low values of RSD (∼3%) adding advantage of the developed SERS sensor biosensor. The SERS sensor will definitely serve to be an excellent fast, selective and sensitive tool for onsite screening of meat products to cease the adulteration.
