Overview

• Teams at the Universitat Politècnica de València and the Universitat de València report a biosensor that identifies airborne pathogens without additional reagents.
• The Talanta paper details LC resonant circuitry that registers frequency and amplitude shifts as viral particles pass through the sensing zone.
• Initial experiments detected the M13 bacteriophage as a proof of concept, with applicability to other pathogens presented as a claim not yet validated in operational settings.
• Researchers estimate a manufacturing cost of about €1, positioning the device for potential integration into early-warning systems in hospitals, schools and public transport, as well as smart buildings and wearables.
• The authors note required advances in selectivity, detection limits and error rates under variable conditions, whereas conventional monitoring still depends on slower, reagent-based air sampling and lab analyses.
