Area of Science:

Forensic Science
Analytical Chemistry
Surface Science

Background:

Effective collection of trace evidence from fingermarks is crucial in forensic investigations.
Surface characteristics like porosity and roughness can challenge traditional trace evidence collection methods.

Purpose of the Study:

To develop and demonstrate a novel method for collecting fingermark material from diverse surfaces.
To validate the applicability of infrared laser ablation coupled with vacuum capture for forensic trace analysis.

Main Methods:

Infrared laser ablation (3 μm) in reflection mode was used to ablate fingermark material.
Vacuum capture with a filter was employed to collect the ablated ejecta.
Analysis was performed using Matrix Assisted Laser Desorption Ionization (MALDI) and Gas Chromatography Mass Spectrometry (GC-MS).

Main Results:

Successful ablation and capture of fingermark standards were demonstrated on glass, plastic, aluminum, and cardboard.
Trace amounts of caffeine (as low as 1 ng) were detected using MALDI.
Condom lubricants, antibacterial peptides, and explosives were successfully identified from fingermarks and direct deposition samples.

Conclusions:

Infrared laser ablation coupled with vacuum capture is a viable technique for forensic trace evidence collection.
This method shows promise for the sensitive detection of diverse chemical compounds from fingermarks on various substrates.
