Non-invasive detection and chemical mapping of trace metal residues on the skin
Residual traces of the metals copper and lead on an individual's skin
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
