Ultra-absorptive nanofiber swabs could improve SARS-CoV-2
test sensitivity

Rapid, sensitive diagnosis of COVID-19 is essential
for early treatment, contact tracing and reducing viral spread.
However, some people infected with SARS-CoV-2 receive
false-negative test results, which might put their and others’
health at risk. Now, researchers reporting in ACS’ Nano Letters
have developed ultra-absorptive nanofiber swabs that could reduce
the number of false-negative tests by improving sample collection
and test sensitivity.
