Abstract
The subject invention provides the materials and methods for synthesizing novel training devices for biological detectors, such as canines, to locate a specific material by recognizing a characteristic scent associated with the material. In an exemplary embodiment, the training devices encapsulate at least one active odorant of certain illicit materials, such as cocaine, within a sol-gel polymer network. By manipulating the process of molecular encapsulation and polymer network synthesis, the novel training devices can reduce the influence of contaminants and dissipate the encapsulated odorant in a controlled fashion, allowing for the added benefit of improved shelf-life as compared to currently available training devices.
