The NAT database (Non-Animal Technologies) recently launched by Doctors Against Animal Experiments (DAAE) gives an overview about animal-free research technologies that are developed all over the world. This database currently contains 250 entries on animal-free methods and will continuously be updated. It is freely available at in English or German and all entries are free for download and sharing. 

Entries contain a short abstract of the respective technology as well as information on contact persons including affiliations and references such as peer-reviewed publications or press releases from universities and research institutes. Commercially available technologies and research models such as microphysiological systems or advanced human cell culture models are also included.  

The NAT database is supposed to inform scientists, regulators, and politicians, as well as the general public, about the power and the advantages of non-animal technologies. Users can run a full text search or use different filter options such as research areas (e.g., oncology, toxicology, or drug development) or research models (e.g. organ-on-a-chip, 3D bioprinting, or computer models). The NAT database also enables a specific search for validated methods, which are additionally labelled in case of regulatory acceptance for safety testing by ECVAM or OECD.
