Our New Technology
By using an innovative non-birefringent capture tape, our new method makes it possible to perform polarising microscopy analysis on a fibre taken from a crime scene without interference from the background substrate. Although fibres are currently collected at crime scenes using adhesive tape, the tape itself is also bifringent, so it is necessary to transfer individual fibres from the tape to a glass slide and coverslip for examination under crossed polars. This procedure is time-consuming (and therefore expensive), requires a high level of skills and increases the risk of contamination leading to the risk of a court rejecting the evidence.
Methods to manufacture and use the films have been devised.
The direct analysis of fibres on the collecting tape will make the examination of fibres much faster, easier and more cost-effective, enabling fibre analysis to become a routine method in criminal investigations. By overcoming existing practical difficulties, it will also be feasible to construct a database of fibres using existing resources for routine use in forensic examinations.
Forensic fibre analysis. The method may also be useful for analysis of fibres in the garment and textile industry.
