Design and characterization of impedance based e. Coli sensor
Foodborne illness has become a concern due to high disease rate and huge losses caused. It is critical to detect and identify the pathogen in food by using sensor. However the conventional methods for pathogen detection are quite time-consuming, costly and label-dependent. This paper presents the de...
