The recent pandemic situation around the globe has exposed limitations in traditional virus detection methods, characterized by sluggishness and low sensitivity. This project proposes op- tical fiber biosensors for viral pro- tein detection to overcome these chal- lenges. The design process is based on using the optic fiber sensors and test- ing their sensitivity abilities in differ- ent mediums. In theory, these biosen- sors offer high sensitivity, specificity, and real-time capabilities, combining nanotechnology, biotechnology, and optical engineering. Testing will val- idate their performance in real-world applications. This innovation promises faster, more accurate virus detection, impacting healthcare, food safety, and environmental monitoring. Therefore, the primary purpose of this paper is to propose the design of optic fiber sen- sors for the detection of viral viruses.
