Face Mask Sensor to Detect COVID-19

Diseases, General, Good products - Bad products

Our breath holds a multitude of biomarkers, including potentially those indicating the presence of SARS-CoV-2, the virus responsible for COVID-19. Those infected with the virus are prone to exhale proteases, enzymes that speed up the breakdown of proteins, related to the new virus. This has led researchers at University of California, San Diego to work on developing a wearable sensor that can be attached to masks to detect the presence of these proteases and therefore the COVID-19 virus.

“In many ways, masks are the perfect ‘wearable’ sensor for our current world,” said Jesse Jokerst, professor of nanoengineering at UC San Diego, who is the lead researcher of this project, in a press release...

Artificial Attachments for Immune Cells Help Kill Tumors

Diseases, General, Good products - Bad products

Though immune cells have the capabilities to kill cancer cells, they’re often thwarted by cancer’s ability to evade detection. Researchers at Pennsylvania State University have now developed engineered natural killer cells that have a much better ability to find and kill cancerous cells.

“We explored a novel method to engineer natural killer cells,” said Yong Wang, professor of biomedical engineering and one of the developers of the new approach, in the announcement. “This technique significantly improved the recognition and killing of target cancer cells.”

Wang and team developed molecular add-ons for white blood cells called polyvalent antibody mimics (PAMs). These PAMs are structured from DNA to produce a scaffold that features multiple branches...
