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 method for determining the quality of a liquid sample, including the following:
causing a portion of said liquid sample to flow in a predetermined direction in a liquid delivery element; positioning a conductive element such that it is not in direct contact with either said liquid sample or said liquid delivery element, wherein said conductive element is adapted to be in electrical communication via a single electrical connection with a passive electrical metering device; recording electrical readings with said electrical metering device; comparing said electrical readings with predetermined electrical reading values associated with high quality and low quality samples of said liquid; and, determining a quality of said liquid as a function of electrical readings associated with said liquid as compared to said electrical reading values associated with said high quality and low quality samples of said liquid.
