Abstract:
Label-free microwave resonator-type biosensors covered with polyclonal anti-Escherichia coli antibodies are presented. The sensors‘ construction provides high sensitivity on the bacteria detection, whereas the utilization of specific antibodies ensures selective bacteria binding. Two types of biosensors are studied to explore the benefits of microwave sensing: the first one, in which increased sensitivity on the bacteria detection is obtained due to the differential excitation of the resonating conductors, and the second one, in which a multi-resonant character increases the probability for the bacteria detection.
