Crime Science Technology (CST) develops innovative solutions for identifying persons and securing of documents and products. These solutions are based on innovations developed with the CNRS (French National Center for Scientific Research) and the Ecole Normale Supérieure de Cachan. In the forensic field, our expertise also relies on numerous synergies with public institutions such as the French Forensic Medicine Institute and the INPS (National Institute for Forensic Science). Moreover, it is supported by ongoing exchanges with Technical and Scientific Polices abroad. CST has developed and markets since 2013, the LUMICYANO : the first one step fluorescent cyanoacrylate used for development of latent fingerprints, a deemed revolutionary process. It is already adopted by several scientific polices in the world such as the French Police, the FBI or Scotland Yard. CST is also developing a range of authentication technologies from the development of the synthesis of fluorescent molecules for securing identity titles, trust securities, banknotes and products.
