Technical note: latent fingermarks, colloidal gold and multimetal deposition (MMD). Optimisation of the method.
Operational details and optimisation of the colloidal gold or multimetal deposition technique (MMD) for the detection of latent fingermarks on non porous and porous surfaces demonstrate the power of the method. Control of particulate size, pH, reagent, handling are shown to be essential. A difficult case example illustrates the potential of MMD.
