Sumary of Optical techniques offer fast, efficient COVID-19 detection:
- Without the prospect of herd immunity on the immediate horizon, speedy detection for COVID-19 remains imperative for helping to curb the pandemic.
- Researchers from the University of Texas at Austin and Omega Optics Inc. investigated the opportunities and challenges in developing rapid COVID-19 sensing techniques.
- They discuss the prospects of optical biosensors for point-of-care COVID-19 testing in the journal Applied Physics Reviews, from AIP Publishing.
- “Due to growing cases resulting from more transmissible variants around the world and the need to prevent and control cases and outbreaks when they arise, we should be utilizing rapid testing more commonly to detect and stop the spread before hitting the transmission peak,” said Aref Asghari, one of the authors.
- One of the most promising solutions to accurate rapid testing is using optical biosensors.
- “In case of COVID-19, the viral load at the onset of infection can be low enough to not be detected by many commercially available methods,” Asghari said.
