Hg Ion Detection with Monolayered Graphene and Gold in a Microfluidic Channel

Abstract:

Detection for aqueous contamination of mercury is important for its risk for human and environment. We report the detection ofHg²⁺ ionswith graphene and gold in a microfluidic channel. The flow-induced voltage was measured in a microfluidic chip fabricated with a graphene and gold embedded between metal electrodes.The lowest mercury ion concentration detected by the sensor is 10^-8M with a fast response time.Our sensor can overcome the limitations of previous techniques such as portability, quick response time.
