Abstract
A method of detecting the vapors of particular organic materials, such as narcotic vapors, in which a test plate is provided having a surface coated with an antibody specific for a particular organic material. The test plate is exposed to atmosphere in a region where the presence of the organic material is suspected so that, if vapors of the particular organic material are present, the material will react with the antibody and cause an observable change in the optical properties of the test plate.
