Design outperforms traditional cotton and flocked swabs in collecting pathogens, including SARS-CoV-2Researchers at the University of Nebraska Medical Center have developed highly absorbent nanofiber swabs that perform better than traditional cotton or flocked swabs.
In head-to-head tests, the nanofiber swabs showed improved absorption and release of a variety of samples including cells, bacteria, and viruses.
Unlike traditional swabs, nanofiber swabs were able to collect SARS-CoV-2 virus from diluted samples.
The enhanced properties of the nanofiber swabs may help improve the overall accuracy of diagnostic tests.
Additional applications include use in forensic sciences, where obtaining small molecules such as DNA can be exceptionally challenging.
