Abstract
In the present study, a new approach towards the evanescent wave-based fiber optic biosensor using Gaussian beam is investigated for the detection of Bilirubin. The sensor structure consists of an unclad multimode fiber of 50 µm and followed by 90 µm of Bilirubin layer. Here Bilirubin is used as a sensing layer and and a method based on wave theory is used to analyze the high-order modes in the optical fiber and to achieve the theranostics application in hyperbilirubinemia. The proposed biosensor intends to improve in the existing fiber optic based sensors in terms of sensitivity and resolution for the detection of Bilirubin. The proposed idea will result in a better screening platform to identify the hyperbilirubinemia by optically assessing the earlier stage of the hyperbilirubinemia.
