The Nanomaterials Fractal Characterization and Bioforensic Science

Nanotechnology and nanomaterials are beginning to have an impact on the bioforensic science, regarding handling of evidence at crime scenes, its analysis in the laboratory and its presentation in the courtroom. Many different nanomaterials are used for processing of the samples, as DNA, gun powder residues, body fluids etc. Nevertheless, nanopowders, especially luminescent, are the most important for the fingerprinting method. The application of each nanomaterial in the forensic examination depends on its structure and properties, which can successfully be determined by applying fractal nature analysis, as an excellent method for micro and nanomaterials characterization. In our research we successfully synthesized photoluminescent Bi, Y and Ag zeoliteLTA topology nanopowders, which could be used for taking fingerprints from different materials, and therefore, they should be well characterized by fractal analysis. This article aims to highlight some of the major advances in forensic science brought about by nanomaterials fractal characterization, but is not exhaustive of the subject matter.
