Tiny devices made of DNA detect cancer with fewer false alarms

A new cancer-detecting tool uses tiny circuits made of DNA to identify cancer cells by the molecular signature on their surface. The circuits work by attaching to the outside of a cell and analyzing it for proteins that are more abundant on some cell types than others. The devices distinguish cell types with higher specificity than previous methods, giving researchers hope their work could improve diagnosis, or give cancer therapies better aim.
