Showcasing analytical science in the forensic fight against crime
This Editorial introduces the web collection on Security and Forensics, guest edited by Craig Banks and Jason Birkett.
Enhanced imaging of developed fingerprints using
mass spectrometry imaging
Imaging mass spectrometry can be used to enhance the visualisation of latent fingerprints that cannot be satisfactorily developed by conventional methods.
Biocatalytic analysis of
biomarkers for forensic identification of ethnicity between Caucasian and African American groups
A biocatalytic assay analyzing the simultaneous presence of creatine kinase and lactate dehydrogenase recognizes biofluids of different ethnic origins for forensic applications.
Advanced statistical analysis and discrimination of gunshot residue implementing combined Raman and FT-IR data
Raman and Infrared spectra were collected from the same gunshot residue particles and combined into one spectrum. The combined approach was found to enhance statistical discrimination.
Forensic proteomics of poxvirus production
The field of microbial forensics has recently sought to develop methods to discern biological signatures to indicate production methods for biological agents.
Detection of methamphetamine in indoor air using dynamic solid phase microextraction: a supplementary method to surface wipe sampling
Dynamic SPME sampling of air followed by GC-MS analysis can detect airborne methamphetamine at former clandestine methamphetamine laboratories and thereby supplement wipe-sampling.
Evaluation of the multimetal deposition process for fingermark enhancement in simulated operational environments
A fingermark developed using MMD on realistically handled cling film.
Raman spectroscopy for the differentiation of lipstick traces
The application of Raman spectroscopy for the identification of trace lipstick forensic evidence is demonstrated.
Development and validation of a presumptive colour spot test method for the detection of
piperazine analogues in seized illicit materials
A novel colour spot test employing the 1,2-naphthoquinone-4-sulphonate (NQS) reagent was developed and proposed for use by law enforcement to screen piperazine analogues in seized materials.
Forensic electrochemistry: the electroanalytical sensing of Rohypnol® (
flunitrazepam) using screen-printed graphite electrodes without recourse for electrode or sample pre-treatment
The mother of all hangovers: we demonstrate a simple electrochemical screening methodology for Rohypnol in drinks and beverages using screen-printed sensors.
Preliminary studies into the effect of environmental degradation on the characterisation of automotive clear coats by attenuated total reflectance infrared spectroscopy
Environmental exposure of automotive clear coat samples over an eight-month period does not affect classification and prediction of class membership by a rapid, simple ATR FT-IR analysis in conjunction with chemometrics.
Ambient pressure thermal desorption ionization
mass spectrometry for the analysis of substances of forensic interest
Ambient pressure thermal desorption ionization mass spectrometry is presented as an analytical tool which could possibly provide high-throughput identification and analysis of forensic samples.
Solid-state Forensic Finger sensor for integrated sampling and detection of gunshot residue and
explosives: towards ‘Lab-on-a-finger’
The article demonstrates the fabrication and characterization of a wearable all-solid-state fingertip sensor for rapid on-site screening of explosives and gunshot residues.
solid phase microextraction analysis for airborne methamphetamine: quantitation using isotopically substituted methamphetamine
This paper reports two methods for calibrating SPME samplers for airborne methamphetamine using a new vapour generator design.
drugs in latent fingermarks by mass spectrometric methods
Drug detection in latent fingermarks by two MS methods.
Effect of hydrogen peroxide oxidation systems on human urinary
Hydrogen peroxide oxidation systems such as peroxidase peroxide system and Fenton's system inflict significant effect on endogenous urinary steroids. These findings have implication in doping control drug testing programs.
Time domain nuclear magnetic resonance: a key complementary technique for the forensic differentiation of foam traces
A method capable of discriminating apparently similar fragments of polyurethane foam is proposed, which could spur the exploitation of such materials as contact traces in a forensic context.
Urine adulteration: can bleach be used to mask MDMA use?
The chemical reaction between MDMA and bleach in urine produced N-chloroMDMA, which can potentially be used as a marker of MDMA abuse in bleach adulterated urine specimens.
A new quantitative method for gunshot residue analysis by ion beam analysis
A new, faster method using a scanning proton microbeam is presented for the non-destructive, quantitative analysis of the elemental composition of single gunshot residue particles.
A high-throughput multi-class
liquid chromatography tandem mass spectrometry method for quantitative determination of licit and illicit drugs in whole blood
A rapid generic method was developed and validated on 51 frequently detected drugs in human blood.
p-Dimethylaminobenzaldehyde: preliminary investigations into a novel reagent for the detection of latent fingermarks on paper surfaces
p-Dimethylaminobenzaldehyde reacts with latent fingermark deposits on paper surfaces to yield yellow-brown impressions of ridge detail which are photoluminescent when viewed under blue-green light (490 nm) with an orange filter (OG550).
Spectroscopic imaging based approach for condom identification in condom contaminated fingermarks
MALDI MSI based multidisciplinary approach for condom brand identification from condom contaminated fingermarks.
