20090275143 | NANOSTRUCTURE ARRAY AND METHODS OF USE FOR EXPLOSIVE DETECTION - In various embodiments, the present disclosure provides a method of detecting triacetone triperoxide. In a particular implementation, the method includes providing an array of titanium nanostructures that include a sensitizing agent. The array is contacted with a fluid sample, such as vapor sample. The resistance of the array is measured. The measured resistance of the array can be used to determine whether the sample includes triacetone triperoxide. The nanostructures are, in some cases, titania nanotubes. The sensitizing agent is, in a specific example, zinc. The present disclosure also provides a triacetone triperoxide sensor that includes an array of nanostructures, at least a portion of which are sensitized with a sensitizer, such as one or more of Li | 11-05-2009 |
