A fluid jet may be delivered by an outlet to dislodge particles from an object, such as a person. An image sensor may determine a target location on the object for delivering the fluid jet. In some embodiments, the image sensor may locate particles of interest to determine the target location. A steering mechanism may direct the fluid jet, so that it impacts the target location. The dislodged particles may then be captured for analysis. A distraction mechanism may distract the object and/or mask the sound of the fluid jet to prevent the object from realizing the fluid jet has been delivered. Additional substances and/or tags may be delivered by the outlet to the object and/or particles. |
