Nanoparticles: A serious threat to our health and the environment

As a manufacturer of medical keyboards, Man & Machine opposes the use of nanosilver in keyboards. Despite its effectiveness against certain bacteria, its use poses a significant risk.
Given the many questions surrounding the potential dangers of nanosilver, Man & Machine is strictly against its use in keyboards. For this reason, the company only offers keyboards that are free of nanosilver. Nevertheless, nanoparticles are used in the medical field to eliminate bacteria. But researchers are sounding the alarm because nanosilver can have an impact on our health and the environment. Man & Machine believes that the precautionary principle must be applied to protect patients, hospital staff and nature from any risk.
Nanoparticles are so small that they can cross biological barriers and penetrate body cells. Inhalation, ingestion or transcutaneous transfer of the particles are potentially dangerous. In a recent interview with Belgian radio station “La première”, Olivier Toussaint, “Nanotoxico” project coordinator at the University of Namur, Belgium, reported worrying results that his team had achieved in tests on cells. They indicate that nanoparticles promote the formation of free radicals. These are highly reactive molecules that can attack DNA. At the same time, researchers at the University of Lausanne found that nanoparticles have the same effects as asbestos (Smith & Jones. The Effects of Nanoparticles on the Human Body 2011).
There is no specific disposal process for waste materials containing nanoparticles, although nanosilver is produced in large quantities. A study also shows that the particles destroy beneficial bacteria in water bodies. It is not known whether nature can withstand the stress of nanosilver. That's why it's important to be aware of the long-term effects of nanosilver.
Until experts safely rule out the risks of using nanoparticles, Man & Machine will not incorporate antibacterial additives into their manufacturing process. Their silicone keyboards are fully sealed, waterproof and can be cleaned with alcohol or other disinfectants. They are an effective solution against the spread of bacteria and germs and take into account the safety of patients, staff and the environment.
