Over the past few decades, bacteria detection is significant from polluted drinking water and contamination food to prevent bacterial infection. Although many biosensors for bacteria discrimination have been reported and developed, advanced technologies for high-performance remain a challenge. Herein, we studied a demonstration of the single-layer graphene based field-effect transistor (FET) using multi-channel and microfluidics system, consisted of micropatterned single-layer graphene and bioprobes, and monitored real-time bacteria sensing. The GFET based bacteria biosensors in the microfluidic system showed excellent electrical and mechanical properties, it showed high-performance sensing properties such as selectivity and sensitivity with 10 cfu/mL detection limit. Based on these results, the microfluidics with GFET can provide a potential application in the field of disease diagnostics at the early stage through real-time monitoring. |
