Evaluation of a solvent-free p-dimethylaminobenzaldehyde method for fingermark visualisation with a low cost light source suitable for remote locations
MetadataShow full item record
The guidelines set forth by the International Fingerprint Research Group were used to plan and conduct the evaluation of a dry contact p-dimethylaminobenzaldehyde (DMAB) approach to the treatment of latent fingermark deposits on porous substrates. Extensive investigations into the development method and its subsequent use across a range of conditions and substrates showed that the dry contact DMAB method is not as sensitive as the recommended ninhydrin techniques. It was found that these guidelines provided a practicable framework for the implementation of method optimisation and comparison studies. Illumination in the form of a cheap LED light source was shown to be a promising alternative to the much more expensive Rofin Polilight®, especially in teaching or remote environments.
