High-performance and low-cost lung cancer sensor array based on self-assembled graphene

Abstract

The lung cancer sensor array (LCSA) based on layer-by-layer (LbL) self-assembled graphene presented in this paper is capable of detecting different lung cancer biomarkers selectively with advantages of high sensing performance and low cost due to graphene inherent properties and self assembly technique. According to the resistance change of graphene, the detection limit of LCSA is down to 0.1 pg/mL.
