(Bio)polymers, Dextran, Hydrangea macrophylla, Latent Fingerprints, Forensics


Biopolymers have numerous advantages, such are biodegradable, non-toxic, non-inflammatory and biocompatible properties, and, therefore, have a potential for various applications. In this paper dextran-based biopolymer powder, obtained from Hydrangea macrophylla liquid anthocyanins extract by ultrasonic extraction and simple precipitating method, was synthetized and characterized in order to determine its properties and potential application. ATR FT-IR analyses showed interactions between components of the system. Optical microscopy suggested that prepared biopowder formulation was small and somewhat uniform in size, and also showed its easy binding to the fingerprint residues. Additionally, prepared biopolymer powder was used to visualize latent fingerprints left on different non-porous and semi-porous surfaces, i.e. flat wood, glass, plastic and rubber. The results demonstrated the potential of obtained dextran-based biopowder to complement routinely applied systems in developing latent fingerprints.
