The Nanomaterials and Biotechnology research team of CTU UCEEB has completed a pioneering project in the field of criminal odorology, in collaboration with the joint-stock company AMBIS College. As a result, the team obtained a patent for unique nanofibre collectors for odour traces and a prototype head sensor for brain activity of specially trained service dogs that evaluate them. This development opens up new possibilities for security forces, enabling further research and use of scent traces in various applications.
