Project background:

Nanotechnology is science, engineering, and technology conducted at the nanoscale, which is about 1 to 100 nanometers. Due to their small size, nanoscale particles exhibit novel physical characteristics compared to the same bulk chemical without nanoscale features. Nanomedicine is simply the application of nanotechnologies in a healthcare setting and the majority of benefits that have already been seen involve the use of nanoparticles to improve the behaviour of drug substances.   As in all fields of medical research, new methods, compounds and substances are widely tested in animal models first. Many of these experiments are classified as moderately and even severely distressful to the animals. Therefore, the study by Ursula Sauer supported by the Animalfree Research tried to answer the question whether such animal experiments are truly the only means to answer the scientific questions addressed in nanotechnology or if there are sufficient in vitro alternatives.
