New testing system uses Janus particles to rapidly and accurately detect COVID-19

The importance of testing for diseases was thrust into the limelight during the COVID-19 pandemic. Many of us have undergone a PCR (Polymerase Chain Reaction) or ELISA (Enzyme-Linked Immunosorbent Assay) test within the past four years.

Yet these forms of testing are far from perfect. They require large sample volumes, involve complex procedures, and even pose a risk of exposing the tester to the virus.

Now, a group of researchers has developed a new quantitative testing system called the "Express Biochecker," which provides a simple, rapid, and low-cost method for detecting the coronavirus N protein.

This new system, which incorporates advanced microfluidic technology, is not limited to the coronavirus—it is expected to be applied to other viral illnesses such as influenza and hepatitis in the future. The research is published in the journal Langmuir.
