Sensor, which has gained considerable attention, is designed based on the distinctive properties of diverse nanomaterials in linking with natural or artificial molecular recognition units [7]. Doping heteroatoms, such as boron and nitrogen, in graphene and carbon nanotubes have yielded results that are of academic interest and practical value [8–12]. Graphene quantum dot modification has significant application in the field of analysis and biological imaging. Photoluminescent sensors have showed the more important position because of operational simplicity, realtime detection, high-throughput process, and good sensitivity
