A new, highly fluorescent dye was synthesised using oleylamine combined with a perylene dianhydride compound. The new dye was characterised by 1H NMR, UV-vis spectroscopy and fluorescence spectroscopy as well as quantum yield. The dye was absorbed onto titanium dioxide nanoparticles for use as a fingerprint detection powder. The new fluorescent powder was applied to latent fingermarks deposited onto different non-porous surfaces and compared with commercial fluorescent powders. The powder exhibits strong fluorescence at 650-700 nm under excitation at 505 nm. On glass surfaces, the new powder gave images showing tertiary-level detail of the fingermark ridges with almost no background development. Compared with current magnetic fluorescent powders, the new powder was slightly weaker in fluorescence intensity but produced significantly less background development, resulting in good contrast between the fingermark and the substrate. © 2007 Elsevier Ireland Ltd.

Abstract: In the present age of heightened emphasis on counter terrorism, law enforcement and forensic science are constantly evolving and adapting to the motivations and capabilities of terrorist groups and individuals. The use of biological agents on a population, such as anthrax spores, presents unique challenges to the forensic investigator, and the processing of contaminated evidence. In this research, a number of porous and nonporous items were contaminated with viable anthrax spores and marked with latent fingermarks. The test samples were then subjected to a standard formulation of formaldehyde gas. Latent fingermarks were then recovered postdecontamination using a range of methods. Standard fumigation, while effective at destroying viable spores, contributed to the degradation of amino acids leading to loss of ridge detail. A new protocol for formaldehyde gas decontamination was developed which allows for the destruction of viable spores and the successful recovery of latent marks, all within a rapid response time of less than 1 h.

A complementary intelligence-gathering tool is described for drug-crime investigation. Scientific analysis and interpretation of packaging materials from seized shipments of illicit drugs will assist law enforcement by creating a more holistic description of each seizure, thus allowing further inferences to be drawn and ultimately assisting in a more thorough understanding of the flow of drugs to or within a particular jurisdiction. The approach is intended as an extension to chemical and physical profiling methods already applied to the actual seized drugs by many law enforcement organisations around the world. Adhesives from 98 rolls of packaging tape were analysed by pyrolysis gas chromatography-mass spectrometry (PyGCMS) for the purposes of determining the types of polymers commonly found in such samples. Using these results as an example, models outlined within this document describe how drug and packaging analysis can complement each other, and how such data can be used in an intelligence capacity. Some limitations of the approach are also identified and discussed.

Hyperspectral (chemical) imaging collects spectroscopic data in a two-dimensional spatial format. The potential application for the determination of the age of bruises is demonstrated and compared to reflectance probe spectrophotometry as well as photography. Blood was deposited on white cotton cloth or injected subcutaneously into pig skin to simulate a ‘fresh bruise’. A mixture of blood and bile was used to simulate ‘old’ bruises. On the cloth background all the photographic methods clearly separated the two groups of samples (i.e. ‘blood only’ from ‘blood plus bile’). However, on the pig skin the two groups could be separated by one of the photographic methods only. Separation of blood from blood and bile mixtures was obtained on the cloth and skin backgrounds using spectrophotometry and hyperspectral imaging. In a test using serial dilutions of blood and bile mixtures, the hyperspectral system performed slightly better than the spectrophotometer. The former also had the advantage of imaging a wider area and providing spatial data. Hyperspectral (chemical) imaging and spectrophotometry are superior to photography for the detection of bilirubin on a background of skin (due to the presence of yellow chromophores); this technology combined with mathematical analysis of the spectral data warrants further investigation.

1,2-Indanedione was first proposed as an amino acid reagent for latent fingermark detection in 1997. Since that time, research groups around the world have undertaken and reported on studies aimed at optimizing the technique and comparing the results obtained with both ninhydrin and DFO development. There has been no general consensus in terms of preferred formulation, development conditions, metal salt treatment, observation conditions, and relative performance compared to conventional techniques. In this study, a new indanedione-zinc formulation is proposed that provides improved detection capabilities compared to DFO, with results that are less dependent on the relative moisture content of treated fingermarks.

1,2-Indanedione is an emerging fingermark reagent used on porous surfaces. The general consensus is that this reagent is at least as sensitive as DFO, with some research showing higher sensitivity for 1,2-indanedione as opposed to DFO. However, a number of discrepancies existed in the literature as to which formulation and which development procedure produces optimal results. This project set out to investigate the best formulation and development procedure under Australian conditions, encompassing all published recommendations as well as some novel approaches. 1,2-Indanedione formulations were compared with respect to initial colour, fluorescence, concentration of reagent, acetic acid concentration, and the effect of different carrier solvents. Numerous development conditions were investigated, including a conventional oven, a heat press and humidity. Further enhancement using metal salt treatment and liquid nitrogen was also evaluated. The heat press set at 165 °C for 10 s proved to give the best initial colour and most intense luminescence. Secondary metal salt treatment improved initial colour and luminescence. The Polilight, the VSC 2000, and the Condor Chemical Imaging macroscope have been used to detect the fingerprints developed with 1,2-indanedione on a variety of high- and low-quality porous and semi-porous surfaces, with impressive results overall. Laboratory and field tests were conducted to compare 1,2-indanedione with DFO and ninhydrin as well as to investigate the position of 1,2-indanedione in the sequence of reagents for fingermark detection on porous surfaces. Overall, 1,2-indanedione proved to be a viable alternative to traditional methods for the detection of fingermarks on porous surfaces, with more fingermarks being developed using this reagent on real samples than both DFO and ninhydrin and a combination of the two reagents. © 2006.
