DEVICES AND METHODS FOR IDENTIFYING A BIOLOGICAL OR CHEMICAL RESIDUE IN AN AQUEOUS SAMPLE

摘要

The invention discloses methods and devices for rapidly detecting a biological or other residue in a liquid sample. In some embodiments of the instant invention, a single electrode is employed to contact a flowing aqueous solution, with electrical outputs being recorded by an electrical metering device. Injection or flow of sample leads to changes in solution electrostatic behavior; those changes are recorded in the metering device, with absence of predetermined residues or targets yielding the highest signals. General and specific target detection may be performed with various embodiments of the instant invention.

主权项

1. A device for identifying the presence of a biological or chemical residue in a liquid sample, including:
a flowing liquid sample; an electrically conductive element disposed partially in proximity to said flowing liquid sample; an electrical meter adapted to be in electrical communication with a dry region of said conductive element through the agency of a single electrical terminal; and, a controller element adapted to receive readings from said meter and provide a signal to a user as to a presence of said residue in said liquid sample.
