Abstract
The system includes a liquid transport structure configured to hold a sensor for detecting one or more components in a liquid. The liquid transport structure includes a reservoir configured to hold a liquid within the liquid transport structure and a channel configured to transport a liquid held in the reservoir to a sensor held by the liquid transport structure.
Claims61
An apparatus for use with an assay, comprising:
- a liquid transport structure configured to hold a sensor for detecting one or more components in a liquid, the liquid transport structure having;
- a reservoir configured to hold a liquid within the liquid transport structure;
- and
- an outlet channel configured to transport a liquid held in the reservoir to a sensor held by the liquid transport structure.
1 more element
An apparatus for use with an assay, comprising:
- a liquid transport structure having a reservoir configured to hold a liquid within the liquid transport structure;
- and
- an outlet channel configured to transport a liquid held in the reservoir to a chamber within the liquid transport structure.
A sensor, comprising:
- an electrode support including a first support region spaced apart from a second support region;
- one or more electrodes positioned on the first support region;
- and
- one or more of the electrodes positioned on the second support region.
1 more element
A method for performing an assay, comprising:
- changing the pressure on a liquid stored in a reservoir of a liquid transport structure so as to transport at least a portion of the liquid from the reservoir into a chamber within the liquid transport structure.
The method of claim 56, further comprising:
- applying a potential between a working electrode and a reference electrode of the sensor while monitoring current passing through a circuit that includes the working electrode, the liquid and a counter electrode of the sensor.
A method for performing an assay, comprising:
- applying one or more liquids to a sensor such that a target agent bonds to the sensor along with one or more non-target agents, the sensor configured to detect a component in a liquid and including two or more electrodes positioned on a sensor support;
- and
- removing agents from the sensor such that the portion of the non-target agents removed is larger than the portion of target agents that are removed.
