RF Sensor with Graphene Film for HRP Concentration Detection
نویسندگان
چکیده
This paper presents a radio-frequency (RF) antenna as sensor to detect Horseradish peroxidase (HRP). At the core of proposed approach is graphene film deposited on stub connected an RF antenna. The doctor bladed stub. then properly chemically functionalized in order presence We validate proof-of-concept operation HRP concentration detection by measuring frequency shift reflection coefficient using very small (0.03 mM 0.6 mM).

5-fluorouracil is a widely used anticancer drug with many side effects on humans, and hence its analysis in biological samples is very important. Accordingly, a novel sensitive electrochemical approach was fabricated by incorporating graphene quantum dots (GCD) and 1-butylpyridinium bromide (BPBr) in the formulation of a carbon paste electrode (GQD/BPBr/CPE). The GQD was synthesized and charact...
