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.
