From: Chemically Functionalised Graphene FET Biosensor for the Label-free Sensing of Exosomes
Schematic of the functionalised biosensor with microfluidic integration, showing the different doping levels of the covered and uncovered graphene as a result of exosome binding. Schematic of the basic structure of an exosome and molecular structure of 1-pyrenebutyric acid N-hydroxysuccinimide ester (PBASE).
