Biosensor for rapid detection of avian (H5N1) influenza
A recent study published in ACS Sensors outlines the capabilities of a novel biosensor designed for the rapid detection of airborne avian influenza (H5N1) and Escherichia coli within a timeframe of under five minutes. This biosensor incorporates a specialized material that combines Prussian blue and graphene oxide on carbon electrodes, facilitating highly sensitive detection. The device is capable of identifying H5N1 at remarkably low concentrations, specifically as few as 56 viral RNA copies per milliliter, and detecting E. coli from as little as 5 bacterial cells per milliliter, achieving an accuracy rate exceeding 90%.
When utilized alongside a bioaerosol sampler, the biosensor can provide estimations of pathogen levels present in the air. This rapid and cost-effective technology has the potential to enhance air quality monitoring and mitigate disease outbreaks, particularly in high-risk environments such as poultry farms.
