Detection of immunoglobulin G (IgG) and immunoglobulin M (IgM) antibodies using circular photonic crystal fiber sensor

Abstract

In this paper, a circular Photonic Crystal fiber (C-PCF) is designed to detect two types of antibodies such as Immunoglobulin G (IgG) and Immunoglobulin M (IgM). Light guiding property of different refractive index (RI) of IgG and IgM are analyzed. For various RI value confinement losses, relative sensitivity and effective mode area are analyzed. The projected CPCF sensor produces low confinement loss and high sensitivity for the detection of IgM and IgG. Realistic execution of the proposed PCF sensor is viable by accessible technology and it is applicable to sense corona virus disease.
