GPC1 and familial pancreatic carcinoma: Wefound that these characteristics of GPC-1 cancerous exosomes are responsiblefor an increase in the number of target exosomes on the surface ofgraphene, leading to an improved signal response of the GFET biosensors.This GFET biosensor platform holds great promise for the developmentof an accurate tool for the rapid diagnosis of pancreatic cancer.
