Abstract: A system for transferring and/or concentrating a sample is provided. The system includes a chamber with a membrane brave positioned within the chamber. An electrode assembly is configured to create an electric field across the membrane to move a charged sample through the chamber such that the sample collects and may concentrate on the membrane. The system may include a plurality of membranes. The system may also include a plurality of microchannels outwardly extending from the channel, where the membrane extends along the plurality of microchannels. Aspects of the invention are also directed to a pipette which may be used to transfer and concentrate a sample on a membrane. Certain embodiments are directed to methods and systems for concentrating a nucleic acid sample.

Abstract: The invention relates to methods and systems for identifying, quantitating and/or analyzing analytes from samples. The analytes may be organic or inorganic in nature and include but are not limited to pathogens such as viruses.
