Applications for electronic noses require a functional layer, known as a binder, to facilitate the sensing and detection of target analytes. However, challenges such as selectivity and cross-sensitivity have been observed, often due to non-specific binding on unmodified sensor surfaces.
In a recently published article, a collaboration between SDU, AmiNIC, and Fraunhofer ISIT illustrates how the functional layer can be effectively controlled. By combining binder position control with analyte adsorption exclusivity, this approach has practical implications. Ultimately, it enhances the repeatability of electronic noses across various applications to achieve reproducible results.
