Photonic Crystal Fiber Based Biosensor for Pseudomonas Bacteria Detection: A Simulation Study

The detection of microorganisms like Pseudomonas are very important as they trigger an infection in human blood, lungs, and different parts the body causing various ailments. In this paper, a surface plasmon resonance (SPR) biosensor based on photonic crystal fiber (PCF) has been proposed to detect presence bacteria with attractive performance characteristics. sensor is designed using simple circular lattice PCF, coated thin chemically stable gold layer. investigation numerically carried out by finite element (FE) simulation tool where highest wavelength amplitude sensitivity found 20,000 nm/RIU 1380 RIU -1 , respectively. shows excellent spectral resolution value 5.26×10 xmlns:xlink="http://www.w3.org/1999/xlink">-6 RIU, ensuring capability identifying small change analyte refractive index (RI) within range 1.33 1.42. also altering diameter air holes, pitch, layer thickness explore variation phase matching conditions due structural parameters. As adept at detecting sample high sensing resolution, can be highly efficient well other organic compounds, biological analytes.
