Using Gene Scissors to Detect Diseases

Sensor prototype can rapidly, precisely, and cost-effectively measure molecular signals for cancer

26-Nov-2019

The CRISPR/Cas technology can do more than alter genes. A research team at the University of Freiburg is using what are known as gene scissors – which scientists can use to edit genetic material – in order to better diagnose diseases such as cancer. In a study, the researchers introduce a ...
