1. A device for dislodging and releasing trace particles of explosives or narcotics from a target surface, comprising:

  • at least one nozzle, the nozzle including;

    a first orifice for the emission of a first jet of pressurized gas directed towards said target surface; and

    at least one second orifice for the emission of a second jet of pressurized gas directed towards said target surface, wherein a velocity of gas emitted by said second jet is equal to or greater than a velocity of gas emitted in said first jet, and wherein said at least one second orifice is at least one of;

    a single orifice coaxial to said first orifice and a plurality of orifices arrayed concentric to said first orifice; and

    at least one controller that controls at least one of the first jet and the second jet, wherein the pulse of said second jet is emitted less than one second prior to the emission of the pulse from said first jet, and the pulse of said second jet is maintained during the pulse of said first jet.
