The use of graphene-based field-effect transistors is one of the most powerful biosensing units for the detection of numerous biological and biochemical analytes. In new work, researchers propose a microscopic model of mycotoxin detection via graphene-based aptasensors enabling improvement of biosensor sensitivity, which is based on the investigation of aptamer interaction mechanism with graphene channel during binding of targeted molecules. The limit of detection is estimated at only 1 ...
