Localized desalting systems and methods

摘要

Example apparatus, systems and methods to desalt a sample are disclosed. An example apparatus includes a substrate and a sensor disposed on the substrate. The sensor has a surface functionalized with a binding agent to interact with an analyte in a liquid sample when the liquid sample is in contact with the sensor surface. The example apparatus further includes an electrode disposed on the substrate to create an electric potential and move ions in the sample away from the surface of the sensor.
