Monitoring health through exhaled breath has long been limited by the difficulty of collecting reliable samples over extended periods. Traditional approaches struggle because breath condensate dries quickly, sensors degrade in humid environments, and wearable systems depend on batteries that require […]
Many diagnostic tests still rely on large optical instruments that sit in centralized laboratories, making it difficult for patients to access rapid, convenient sampling. These systems depend on external lasers, bulky optics, and controlled environments, which limits their use outside
Imagine diagnosing the flu with a simple tongue test. Researchers have developed a prototype sensor that could one day make this possible by detecting viral proteins directly from saliva. The device uses a small, flexible strip coated with antibodies that
Researchers from Universitat Politècnica de València (UPV) and Universitat de València (UV) have developed a compact biosensor capable of detecting airborne viruses in real time, offering a fast, low-cost alternative to traditional lab-based methods. This innovation could significantly improve public
