About technology
The subject of this offer is an invention defining a method of visualizing dactyloscopic traces on an absorbent substrate using a non-toxic final solution based on aggregates of 1,8-diazafluoren-9-one in a polyvinylpyrrolidone polimer and a final solution based on aggregates of 1,8-diazafluoren-9-one in a polyvinylpyrrolidonepolymer for use in this method.
The absorbent substrate includes in particular plain paper or thermal paper.
The search for new ways to visualise dactyloscopic traces and less toxic solutions using the DFO molecules used in these methods is particularly important in terms of the development of forensic science, while also being environmentally friendly.
