Diagnostic multi-layer dry phase test strip with integrated biosensors (“electrostrip”)
First Claim
1. A diagnostic multi-layer dry phase test strip with integrated biosensors for use in measuring more than one analyte in a fluid sample, said test strip comprising:
- (a) a body having a port for introducing a fluid sample;
(b) a spreader layer configured to evenly spread the fluid sample received through the port;
(c) more than one enzyme reaction layer in fluidic communication with the spreader layer;
(d) a first electrode layer in fluidic communication with the more than one enzyme reaction layer, the first electrode layer including at least one electrode for each of the more than one enzyme reaction layer, each of the at least one electrode capable of electrically interacting with the fluid sample, each of the at least one electrode being a counter-electrode, the first electrode layer located on top of the more than one enzyme layer;
(e) an electrically insulating base layer;
(f) a plurality of lead terminals formed on the electrically insulating base layer; and
(g) a second electrode layer, located under the more than one enzyme layer, the second electrode layer in fluidic communication with the more than one enzyme reaction layer, the second electrode layer including at least one reference electrode and at least one working electrode for each of the more than one enzyme reaction layer, each of the at least one reference electrode and at least one working electrode capable of electrically interacting with the fluid sample.

Abstract
A diagnostic multi-layer dry phase test strip with integrated biosensors for use in measuring more than one analyte in a fluid sample includes a body having a port for introducing a fluid sample. Within the body is a spreader layer configured to evenly spread the fluid sample received through the port. The test strip further includes at least one enzyme reaction layer in fluidic communication with the spreader layer. The test strip also includes a first electrode layer in fluidic communication with the at least one enzyme reaction layer. The first electrode layer includes a set of electrodes for each of the at least one enzyme reaction layer. Each set of electrodes is capable of electrically interacting with the fluid sample.
