Abstract
A colorimetric detector for chemical and biological agents or toxins is made of a giant unilamellar vesicle (GUV) having a membrane bilayer which is polymerized to stabilize the giant unilamellar vesicle and to provide extended conjugated polymer backbone, and the GUV has at least one incorporated molecular recognition site for the chemical and biological agents or toxins. The GUVs are about 10-300 microns and preferably made of a polymerizable diacetylenic GUV where the acyl chains are crosslinked. When the agents or toxins bind to the recognition site the detector exhibits a color change. The detector can be used in a colorimetric detector apparatus where the samples can be present in air or in water.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
