I have fingerprints collected on gloves, aluminium foil, jute and cloth as well as large glass slides. How do I image them under an SEM? I tried to cut a small portion of it (Aluminium Foil), gold coat it and then image them but did not get any results.

Hossein Rezaei , I tried something similar but not with print ink. For instance, one of the fingerprint was taken from a subject wearing gloves or the fingerprint was taken on a silk cloth. When doing the SEM Imaging, I see features of the substrate and not the fingerprint itself. My samples are taken from site and always cannot use be through ink.
