Abstract
We have investigated the characteristics of particulates found in fingerprint deposition using a surrogate finger and a custom mechanical testbed with in situ microscopy, describing the residue for several explosives materials as a function of applied force and print number. We attempt to account for the presence of oils naturally found on human fingers using a surrogate material and quantify how it affects the particulate residue. The amounts deposited, their spatial distribution and particle sizes are of direct interest to optical-based detection techniques being developed for non-contact or standoff detection of explosives.
