摘要：
The buoyant-analyte-magnetic (BAM) assay presents a breakthrough in the rapid and ultrasensitive detection of SARS-CoV-2 N-protein in saliva, achieving a detection limit of approximately 37 molecules per 5 µL sample. This innovative method utilizes buoyant microbubbles and magnetic microspheres, allowing for point-of-care deployment with minimal equipment. The BAM assay aligns with WHO's ASSURED criteria, making it suitable for use in resource-limited settings. Its high sensitivity and affordability position it as a promising tool for early detection of infectious diseases, particularly during outbreaks.
