Abstract

Embodiments described herein related to devices and methods for the collection and/or determination of analytes, such as illicit substances including military explosives, explosives, and precursors thereof. In some cases, the device may be a disposable device that incorporates highly efficient sample collection in combination with microfluidic-based chemical analysis resulting in the rapid detection and identification of unknown materials. In some cases, multiple colorimetric detection chemistries may be employed, and the resulting “barcode” of color changes can be used to positively identify the presence and/or identity of the analyte.
