Disinfectant containing nano silver

The antibacterial properties of silver have been known for centuries. Its “healing” qualities were already recognised in Ancient Rome, where silver coins were used to preserve drinking water during a time when no scanning tunnelling microscopes existed and there were no modern methods for testing the mechanical properties of precious metals. Yet the Romans were still capable of discerning the effects of silver as a bactericide and fungicide. Today, we are witnessing a revival in the use of silver along with a rapid rise in popularity, and a wide range of colloidal silver products are available on the shelves of herbal drug stores and pharmacies. Nanobakt Ltd. has taken advantage of the opportunities offered by silver and nanotechnology to produce a new generation of disinfectants under the brand name Nanosept.


How does Nanosept work?

When bacteria encounter silver particles of a few nanometres in size, an oxidation-reduction reaction takes place. Compounds forming the cell walls of the bacteria react to the silver particles – and oxidize them – releasing silver ions from the surface of the particles. As the oxidation occurs, the compounds themselves are transformed, meaning that they are reduced. Because of this transformation, the cell walls protecting the bacteria are breached, giving silver ions easy access to the inside of the bacteria. The silver ions then bond with enzymes that are vital to the bacteria and which catalyse the metabolic processes of the microorganism. As a result, the bacterial enzymes suffer a chemical transformation and can no longer perform their function. Bacteria are thus destroyed as a consequence of the chemical reactions occurring between bacterial enzymes and silver ions.

Surfaces treated with Nanosept continue to remain antibacterial for a long period of time, and microbiological tests have proven that it is effective against bacteria as well as fungi.
