This article describes the composition of fingermark residue as being a complex system with
numerous compounds coming from different sources and evolving over time from the initial …

After over a century, fingerprints are still one of the most powerful means of biometric
identification. The conventional forensic workflow for suspect identification consists of (i) …

Within the past decade, imaging mass spectrometry (IMS) has been increasingly recognized
as an indispensable technique for studying biological systems. Its rapid evolution has …

The suite of techniques which are available with the small accelerators used for MeV ion
beam analysis (IBA) range from broad beams, microbeams or external beams using the …

The first analytical intercomparison of fingerprint residue using equivalent samples of latent
fingerprint residue and characterized by a suite of relevant techniques is presented. This …

The substances deposited from the fingertip onto a surface during contact between them
represent a highly complex range of chemicals that can be exploited in a variety of ways in a …

Latent fingerprints are the unique impressions of various loops, whorls, and arches left
behind when a finger comes in contact with a surface. As a result, fingerprints can be used …

The question of the age of fingermarks is often raised in investigations and trials when
suspects admit that they have left their fingermarks at a crime scene but allege that the …

Latent fingermarks are invisible to the naked eye and normally require the application of a
chemical developer followed by an optical imaging step in order to visualize the ridge detail …

Time-of-flight secondary ion mass spectrometry (TOF-SIMS) has been used in imaging of
small molecules (< 500 Da) in fingerprints, such as gunshot residues and illicit drugs …
