Abstract: The present disclosure describes methods, devices and systems comprising materials comprising dielectrics. In various aspects, electrodes layered or imbedded with these dielectrics provide enhanced properties for a wide range of applications, such as the enhanced separation of analytes, such as biological molecules or particles (nucleic acids, viruses) with an electrokinetic field.

Abstract: In one embodiment, a method for isolating and detection one or more biomarkers of interest on a dielectrophoresis device includes receiving a first biological sample containing one or more biomarkers of interest onto a dielectrophoresis (DEP) electrode array, applying a DEP force through particular electrodes of the DEP electrode array, wherein a strength, direction, and period of time of the DEP force is specific to the one or more biomarkers of interest of the first biological sample, and determining, via a digital sensor, a quantity of the one or more biomarkers of interest of the first biological sample.

Abstract: Provided herein are methods and reagents for functionalization of metallic surfaces, including platinum, gold, palladium, iridium, and rhodium. The methods and reagents provided herein use phosphonic acid or phosphonate ester reagents as a source of attachment for various functionalities, thereby allowing modification of the surface with desired properties. The modified surfaces provided herein are useful for a variety of applications, including prevention of biofouling on metallic surfaces.
