▎ 摘　　要

NOVELTY - The sensor has a polylysine coupling agent fixed on the surface of the graphene transistor channel. The antibiotic aptamer is immobilized on the polylysine coupling agent. The microfluidic chip i.e. polydimethylsiloxane microfluidic chip is placed on the top part of the graphene transistor. The microfluidic chip includes a microfluidic control unit that is connected to a sample inlet and a sample outlet. USE - High performance graphene transistor-based antibiotic sensor. ADVANTAGE - The single-layer graphene on a copper foil is transferred to a substrate by using a camphor-layer structure that is easy to remove as a support layer, the high performance graphene transistor is obtained by performing the micro-nano process, and antibiotic-specific aptamer probes are immobilized on transistor channels and combined with microfluidic chips to obtain highly sensitive antibiotic sensors, so that the problems of complex antibiotic detection process and low detection sensitivity are solved. The sensitivity of the antibiotic sensor is greatly improved, the detection period of the antibiotics is simplified, the detection process is optimized, and rapid and high-sensitivity antibiotic detection and analysis are realized. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) a method for manufacturing a high performance graphene transistor-based antibiotic sensor; (2) a method for performing antibiotic detection by using the high performance graphene transistor-based antibiotic sensor. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a high performance graphene transistor-based antibiotic sensor. (Drawing includes non-English language text).
