N2 - The ion sensitive sensor array (ISSA) based on layer-by-layer (LbL) self-assembled graphene presented in this paper is capable of detecting different ions selectively with advantages of high sensing performance and low cost due to graphene inherent properties and self-assembly technique. According to the conductance change of graphene, the detection limit of ISSA is down to 1 μM, much better than one dimensional carbon nanotube (CNT) sensors. The response time of ISSA is 15 s. The human sweat in vitro testing also confirms the high performance of ISSA.
