DNA Nets Capture Sars-CoV-2 for Detection and Inhibition
A team at the University of Illinois at Urbana-Champaign has developed a DNA net system that can ensnare Sars-CoV-2 and bind to the notorious spike protein. The nets contain aptamers that bind the spike protein and emit an intense fluorescent...

Nanorattles for Rapid Detection of Multiple mRNA Cancer Biomarkers
Scientists at Duke University have developed a ‘nanorattle’ system that allows for the detection of mRNA biomarkers of cancer. The tiny structures consist of gold nanospheres with a surrounding silver nanocage, forming the so-called rattle....
