#Atom-width graphene sensors could provide unprecedented insights into brain structure and function Understanding the anatomical structure
The graphene sensors are electrically conductive but only 4 atoms thick less than 1 nanometer and hundreds of times thinner than current contacts.

#Graphene sensor tracks down cancer biomarkers An ultrasensitive biosensor made from the wonder material graphene has been used to detect molecules that indicate an increased risk of developing cancer.
Results showed that the graphene sensor was capable of detecting 8-OHDG concentrations as low as 0. 1 ng ml-1

With the addition of boron atoms, the boron graphene sensors were able to detect noxious gas molecules at extremely low concentrations, parts per billion in the case of nitrogen oxides and parts per million for ammonia
