1. A detection device for detecting the presence of a bioagent in a fluid, comprising:
- a body defining a first chamber for accommodating fluid therein and a second chamber;
a detection structure disposed in the second chamber of the body, the detection structure generating a predetermined signal in response to exposure to the fluid, wherein the detection structure includes a microcapacitor having first and second terminals for connecting the detection structure to a signal detection circuit; and
a valve interconnecting the first and second chambers, the valve dissolving and becoming a solute in the fluid in response to the presence of the bioagent in the fluid in the second chamber, wherein the valve is a membrane material comprising peptide sequences to serve as recoginition elements for the bioagent to be detected.

Abstract
A detection device is provided for detecting the presence of an agent in a fluid. The device includes a body defining first and second chambers. It is intended for the first chamber accommodating the flow of fluid therein. A first valve is disposed in the body between in the first and second chambers. The first valve opens in response to the presence of the agent in the fluid. A first detection structure is disposed in the second chamber in order to generate a predetermined signal in response to exposure to the fluid.

9. A detection device for detecting the presence of a bioagent in a fluid, comprising:
-
a body defining first and second chambers, the first chamber accommodating the flow of fluid therein; a first valve disposed in the body, the first valve; having a first closed configuration wherein the first and second chambers are isolated and a second open configuration wherein the first and second chambers communicate; and including a polymeric material isolating the first and second chambers with the first valve in the closed configuration, the polymeric material dissolving and becoming a solute in the fluid in response to exposure to the bioagent, wherein the polymeric material comprises peptide sequences to serve as recognition elements for the bioagent to be detected; a first detection structure disposed in the second chamber, the first detection structure generating a predetermined signal in response exposure to the fluid, wherein the first detection structure includes a microcapacitor having first and second terminals for connecting the first detection structure to a signal detection circuit. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A method of detecting the presence of a bioagent in a fluid, comprising:
-
passing the fluid into a body defining first and second chambers, the first and second chambers being isolated from each other by a first valve formed from a polymeric material, wherein the polymeric material comprises peptide sequences to serve as recognition elements for the bioagent to be detected; dissolving the polymeric material into a solute in the fluid in response to exposure to the bioagent in the fluid so as to allow fluid to flow into the second chamber; generating a signal in response to the presence of fluid in the second chamber, wherein the step of generating a signal includes the additional steps of; providing a microcapacitor having an initial capacitance in the second chamber; varying the capacitance of the microcapacitor in response to the presence of fluid in the second chamber; and
detecting the change in capacitance. - View Dependent Claims (17, 18, 19, 20)
