Title:
SEMICONDUCTOR DETECTOR FOR PEROXIDE-BASED EXPLOSIVES
Document Type and Number:
WIPO Patent Application WO/2010/010547
Kind Code:
A3
Abstract:
A device for the detection of a peroxide-based explosive, in particular, triacetone triperoxide (TATP), which is based on a molecular controlled semiconductor resistor (MOCSER) and composed of at least one insulating or semi-insulating layer, at least one conducting semiconductor layer, two conducting pads and a layer of multifunctional organic molecules capable of adsorbing molecules of said peroxide-based explosive. Further is provided an array of semiconductor devices for the selective detection of a peroxide-based explosive, as well as a method for the selective detection of vapors of a peroxide-based explosive in a gaseous mixture using said array. The multifunctional organic molecules are from the group of cyclodextrins, thiols or alkylphosphonates with RPO (OH) 2 wherein R is an aliphatic hydrocarbyl with C6-C22.
