Quartz Crystal Microbalance-Based Biosensor for Rapid and Ultrasensitive SARS-CoV-2 Detection
Summary
A QCM biosensor for the SARS-CoV-2 nucleocapsid protein, with a polyethylene glycol surface chemistry that improves sensitivity and specificity. It gives a result in about 15 minutes with a detection limit of 53.3 TCID50/mL and does not respond to influenza A; SEM, digital holographic microscopy and Raman spectroscopy confirm the surface is stable. The authors present it as a low-cost, open-source platform for settings with few resources.
