By the pattern of the fingerprint of every person on this earth, there is no one duplicates, even twins, which is evidence that it will be able to identify the assailant. Latent fingerprint fingerprint is not visible to the naked eye. Will need to use a different process to recover for example how NI นไฮด and how carbon is to recover a fingerprint, but Nicklaus นไฮด Rin for fingerprints on porous materials. Carbon parts find fingerprints on non-porous Thus, latent fingerprint recovery is complex and hazardous to the operator because the NI นไฮด is cancer and nasal tissue. Carbon black, then a chemical carcinogen and there is a high price must be used carefully.Way group has studied ways to recover latent fingerprints from nature using powder from Thailand because the anchor is also easy to find materials that come from the natural, safe, and interesting to study the ability of latent fingerprint recovery powder particle size from Thailand at anchor.53, 75, 90150180250 mic to make powder, anchor, Thailand can recover latent fingerprints on porous material and porous, no details of the stripes on the latent fingerprints clearly.
