MXENE COATED SURFACE PLASMON RESONANCE BASED PHOTONIC CRYSTAL FIBER SENSOR FOR THE DETECTION OF HIV AND SICKLE CELL ANAEMIA

Abstract

This work suggests the design and structural analysis of Surface Plasmon Resonance (SPR) Based Photonic Crystal Fiber (PCF) Refractive Index Sensor, which has found applications in various domains. The work mainly explores its potential in bio-sensors and also the effect of v 2D plasmonic enhancers are studied and are compared on the basis of Confinement Loss and Wavelength sensitivity. The proposed work explores the potential of MXene, another class of 2D materials, in the detection of Human Immuno deficiency (HIV) Virus and Sickle Cell Anaemia. HIV and Sickle cell anaemia are two of the most dangerous conditions existing in our world. The work is an effort to encourage early detection of these diseases to facilitate effective treatment. The obtained wavelength sensitivities are 10,571.43 nm/ RIU and 3500 nm/RIU for the Gold PCF sensor, and 14,142.86 nm/RIU and 4000 nm/RIU for MXene-Gold PCF sensor for HIV infected cell and Sickle cell anaemia, respectively. The work thus concludes that 2D materials, specifically MXenes are highly effective plasmonic enhancers when used in combination with any plasmonic material like gold, showcases high sensitivity for the application in bio-sensors
