Microwave based resonant biosensors for multiple molecular concentrations quantification

International audienceThis paper presents several microwave based resonant biosensors realized with a microfluidic and thin film microstrip technology. Due to the use of multiple stubs terminated by an interdigitated capacitor, this paper demonstrates that this circuit topology is suitable for multiple and simultaneous molecule concentration measurements. The accuracy study of the measurement is conducted depending on the concentration of glucose and the frequency stub loaded with an aqueous-based glucose solution
