Rapid and accurate viral diagnostics are critical for preventing the spread of infectious diseases and responding effectively to epidemiological threats. Fiber optic sensors provide near real-time measurement capabilities, making them particularly useful for epidemic monitoring and early pathogen detection. The ability to establish sensor networks enables large-scale monitoring, which is essential for widespread diagnostic applications.
This study explores the use of fiber optic sensors based on biofunctionalized microspheres for detecting viral RNA. Through specific surface modifications, such as immobilizing nucleic acid probes, we achieved high sensitivity and selectivity in identifying target sequences. The developed method enabled the detection of viral RNA at a concentration as low as 1 pM, highlighting its potential for ultrasensitive viral diagnostics. The sensor was developed using a single-mode telecommunication optical fiber, making integration into existing fiber optic networks possible, which enhances applicability in realtime medical diagnostics and modern epidemiological monitoring systems.
