Abstract
Described herein are methods directed to the use of the nanodot taggants in detection and/or simulation scenarios. The nanodot taggants are based on quantum dots and may be engineered so as to have particular emission and or absorbance spectral characteristics. The nanodots are extremely small, i.e., on the order of nanometers in size, and thus do not, in some cases, behave as particles, but rather are able to be carried along and through structures like a gas.
Claims11
A method for detecting the characteristics of an explosive reaction comprising:
- exploding a component containing an explosive material and a nanocomponent taggant material;
- releasing at least a portion of the nanocomponent taggant material from the component upon exploding the component;
- emitting at least one predefined radiation frequency from the at least a portion of the nanocomponent taggant material in response to the exploding component;
- and
- detecting the at least one predefined radiation frequency emitted in response to the exploding component.

A process for identifying a target object comprising:
- placing a first panel containing a first nanocomponent taggant in a first liquid to a target object, wherein the first nanocomponent taggant emits at least a first predefined spectral frequency in response to interrogation;
- transmitting first radiation at the target object in order to induce emission of the at least a first predefined spectral frequency from the first nanocomponent taggant in the first panel;
- detecting the at least a first predefined spectral frequency emitted from the target object in order to identify the target object;
- and
- changing a spectral signature of the target object by changing the first liquid containing the first nanocomponent taggant to a second liquid containing a second nanocomponent taggant that emits a second predefined spectral frequency in response to interrogation by second radiation.
