may be elucidated by reaction of rubeanic acid with a gelatine lift
taken from the target area in question, yielding intensely coloured
reaction products. This non-invasive technique has been shown to
offer promise in chemically mapping the distribution of the minute
metal residues across an individual's hand deposited through touching
metal items, a technique with potential forensic significance.
