摘要：

Graphene sheets made by chemical vapor deposition are transferred onto a glass nanopipette to form graphene strips. Two strips are connected at the nanopipette tip end to form a transistor channel. This graphene-based transistor can be operated in a liquid-gating condition, thereby allowing the electrical detection of the pH value of a droplet with submicroliter volume.
