A High Sensitivity and Fast Responsive Fluorescence-Based Device for Detection of Biomolecules to Enhance Security against Biowarfare and Pandemics
Mukund Athmaram
Abstract: A highly sensitive fluorescence-based device has been developed for the detection of biomolecules to enhance security against biowarfare. In response to the escalating threat of biowarfare due to rapid development and heightened international competition, quick detection of hazardous viruses or bacteria becomes crucial for evacuating contamination zones promptly. The device presented in this work is a prototype utilizing photoluminescence spectral analysis principles. Notably, the device exhibits exceptional detection selectivity through the incorporation of different LEDs of wavelengths along with 266 nm laser for excitation and a photomultiplier-based high sensitive detection system. The author highlights the device's responsiveness using standard optically active amino acids, forming the basis for establishing a standard data set for the detection mechanism. The instrument is specifically designed to detect biomolecules in aerosol form, with the added capability of detecting liquid samples. Moreover, the instrument is cost-effective, enabling commercial use in critical locations such as trains, parliaments, and other areas prone to bio attacks. Its deployment promises significant advancements in the security systems of nations.
