Mass‐Produced and High‐Performance Nanowell Biosensor Fabricated via Semiconductor Manufacturing for Rapid and Accurate COVID‐19 Diagnosis in the Clinical Field (Adv. Sci. 33/2026)

Nanowell Biosensor for Rapid Detection of SARS-CoV-2 Antigens The cover depicts a semiconductor-fabricated nanowell biosensor enabling rapid detection of SARS-CoV-2 antigens from clinical samples. Nanostructured electrodes enhance biomolecular interactions, improving sensitivity and signal reliability while minimizing nonspecific effects. Scalable fabrication ensures reproducible performance between devices. This platform supports fast and accessible point-of-care diagnostics, highlighting its potential for at-home detection, widespread clinical deployment and real-time health monitoring.
