    Abstract

    This thesis describes physical and chemical investigations performed on latent fingermarks deposited on non-porous surfaces in order to provide the necessary fundamental underpinnings for future fingermark research. Variation of the physical properties over time was investigated using a novel imaging mode of atomic force microscopy. Spatial distribution of fingermark components was investigated using high-resolution vibrational microspectroscopy techniques. Time-course transformation of squalene in fingermarks stored under different storage conditions was examined using liquid chromatography-high-resolution mass spectrometry.
