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
The present investigation examines a novel dual-core photonic crystal fiber (PCF) for early cancer cell detection that is based on a surface plasmon resonance (SPR) biosensor. The PCF is coated with Au/TiO layers to boost sensor effectiveness by enhancing the adhesion between the fiber and gold layers. The sensor was simulated and analyzed using the COMSOL Multiphysics software, which is based on the finite element method (FEM). Spectral and amplitude interrogations were used to explore the RI fluctuations of various cancer cells. The observed RI values varied within the range of 1.36–1.401. The biosensor’s highest sensitivity was found to be 11,429 nm/RIU for MCF-7 cells using spectral interrogation and 1251.18 RIU for MDA-MB231 cells utilizing amplitude interrogation techniques. Additionally, the sensor shows the maximum resolution for basal cells, which is 8.75 × 10 RIU.
