These biosensors are particularly critical for the development of point-of-care (POC) diagnostic tools, enabling early detection of infectious agents. This review explores recent advancements in nanoparticle (NP)-based biosensors that utilize noble metals like gold (Au), silver (Ag), and platinum (Pt) for viral pathogen detection, focusing on viruses such as SARS-CoV, HIV, hepatitis, influenza, and Zika. It highlights the role of NP-based electrochemical sensors and compares traditional and contemporary detection techniques. The review also examines key performance metrics such as limits of detection (LOD), linear detection ranges, cost-effectiveness, and accessibility, with a special emphasis on their application in POC diagnostics.
