Cover Story: First-generation amperometric xanthine biosensors, assembled via layer-by-layer methodology and featuring xerogels doped with gold nanoparticles, were effective for xanthine detection in both clinical (disease diagnosis) and industrial (meat freshness) applications. Embedding the xerogel layer with a network of alkanthiolate- monolayer-protected gold nanoparticles enhanced biosensor performance, with improved sensitivity, linear range, and response time. Additionally, the biosensors exhibited stable sensitivity and discrimination against common interferent species over time. Signal deconvolution, critical to deciphering xanthine within the natural purine metabolism mechanism, along with the portability, low cost, and small size, are all attributes of the presented sensor.
