Two-dimensional materials such as graphene are not only ultrathin, but also extremely sensitive. Researchers have therefore been trying for years to develop highly sensitive biosensors that utilize ...

Just like other biosensors, a graphene-based biosensor requires a functionalised surface on which only specific molecules can attach. If, for example ...

Researchers developed a method to functionalize graphene using a 1-nm dielectric carbon layer, enabling capture molecules to ...
