A perfect diffusion to preserve the shape of the biological traces.

In the course of a forensic investigation, it is sometimes necessary to collect biological evidence from crime scenes. This task can be more complicated on non-porous surfaces such as television screens, glass, or kitchen and bathroom paints. Thanks to the ultra fine diffusion of its particles, BLUESPRAY allows investigators to reveal traces without altering their shape. Preserving the shape of the trace is essential for investigators, as it will allow morpho-analysts to precisely define the angle and shape of a projection, in order to deduce valuable information. The BLUESPRAY is particularly appreciated by investigators because, in addition to preserving the shape of the traces revealed, it allows a consequent economy of the reagent used during the examination of a place, a house or a vehicle.
