摘要：

An ultrasensitive real-time Fe3+ ion sensor based on carbon quantum dot (CQD)-functionalized solution-gated graphene transistors (SGGTs) is designed. Special functional groups are designed to modify the surface of CQDs, which endows the device with ultra-high sensitivity and excellent selectivity. More importantly, the components of the sensor except the gate electrode can be used repeatedly.
