AB  - Fingerprints are usually classified as patent, plastic, and/or latent. However, detection and visualization of latent fingerprints, as relevant traces found at the crime scene are very important for reliable identification of suspects by law enforcement personnel. Chemical and physical methods have now been used for years for that purpose, but they showed many deficiencies, where the most important one was related to their toxicity. Therefore, researchers are in constant search for producing complementary, less harmful methods, and some novel approaches are based on (bio)polymeric materials exploiting their specific properties. In this paper, dextran-based micropowders obtained from anthocyanin solution by the simple precipitating method were synthesized and characterized. Dextran is widely used in medicinal and pharmaceutical applications, but, up to our knowledge, no study has been reported using this biopolymer as a powder component for the developing agent for latent fingermarks visualization. Besides being biodegradable and biocompatible, dextran shows non-toxic properties and thus prevents detrimental effect on humans often present when commercial chemical and physical methods are being routinely employed, while at the same time reduces the overall cost of the obtained powder system. Four different formulations of dextran-based micropowders were prepared with the aim of evaluating their performances in visualizing latent fingerprints. FT-IR analyses confirmed interactions between components of the systems. Optical microscopy showed that prepared powdered samples were small and uniform in size, while at the same time confirmed their easy binding to the sweat and lipid residues present in the latent trace. The results demonstrated that these novel dextran-based powders have the potential to supplement routinely employed physical systems in detecting and visualizing latent fingerprints.

AB  - Dextran is extensively exploited in medicine and pharmacy, but, currently no studies using this biopolymer as a powder system for enhancement of latent fingerprints were published. In  this  paper  four  different  formulations  of  dextran-based  biopolymer  powders,  obtained  by  simple precipitation of dextran within anthocyanin solution, were synthetized and characterized in order to determine potential of these biopowders in forensic application. Since detrimental effect  on  humans  is  often  present  while  routinely  employing  commercial  dusting  methods,  the  main  advantage  of  prepared  dextran-based  biopowders  are  their  non-toxic  properties,  contributing to the safer/healthier operating conditions. The interactions between components of  the  systems  were  confirmed  by  FT-IR  analysis.  Optical  microscopy  was  used  to  determine  the size of the prepared biopowders, while simultaneously confirmed the interaction between powders and the sweat/lipid residues present in the latent trace. The results demonstrated the potential of novel dextran-based biopowders to supplement routinely employed physical systems in visualizing latent fingerprints.
