Summary:

- This preprint article describes the development of a novel biosensor system that can detect and quantify the presence of SARS-CoV-2, the virus responsible for COVID-19, in environmental samples.
- The biosensor utilizes a combination of engineered bacteriophages and electrochemical detection to provide a rapid, sensitive, and specific method for identifying the presence of the virus.
- The authors report that the biosensor demonstrates high accuracy and sensitivity in detecting SARS-CoV-2 in various environmental matrices, making it a promising tool for environmental monitoring and surveillance of the virus.
