1. A self-contained sampling/testing device comprising:
- a. a sampler for collecting target material from a sample; and
b. a signal generator comprising a dye which binds to said target material to signal the presence of said target material, wherein said sampler contains an absorbent an at the surface of which is positioned a membrane to which the dye is attached either covalently or non covalently.

Abstract
The present invention relates generally to self-contained devices and methods for detecting biological contaminants and, more particularly, to self-contained devices and methods for detecting biological contaminants in relevant settings including, for example, food processing plants, hospitals, medical offices, veterinary offices, and restaurants by using a device or methodology that includes a sampler component and dye component that binds to the biological material in a detectable fashion.

2. A self-contained sampling/testing device comprising:
-
a. a sampler for collecting target material from a sample; and
b. a signal generator comprising a dye which binds to said target material to signal the presence of said target material, wherein said sampler contains an absorbent pad which has the dye attached directly to its surface either covalently or non covalently.

11. A self-contained sampling/testing device comprising:
-
(a) a sampler for collecting biological target material from a sample; and
(b) a signal generator comprising a frequency shift dye of the protein error family, wherein said dye binds to said biological target material and produces a color change upon binding to said target material, unbound frequency shift dye need not be separated from biological target bound frequency shift dye in order to detect the presence of target material, and wherein said sampler contains an absorbent pad at the surface of which is positioned a membrane to which the dye is attached either covalently or non covalently. - View Dependent Claims (12, 13, 14)
