Safe solution: self-cleaning surfaces

Constant cleaning of door handles, elevator buttons or touch screens was of paramount importance even before the pandemic, and since then the disinfection of such surfaces has required increased attention. To meet the demand, several companies developed self-cleaning tools and coatings.

Cleaning of frequently used surfaces can be challenging for any professional team – especially in large facilities. Therefore the use of self-cleaning coatings or surface treatments can be a huge help.

Non-stop hygiene

Among others, Nanotouch markets touchable surfaces that never stop self-cleaning using light-actuated nanocrystals, which create a strong oxidation reaction. This process takes place continuously constantly oxidizing organic impurities.

Unlike traditional disinfectants and cleaners, the NanoSeptic surface does not use toxic substances, heavy metals or chemicals, and nothing is released from it because the nanocrystals are molecularly bound to the material. This technology is used to coat elevator buttons, door handles, touch screens and light switches.

Liquid coatings – such as e.g. Nanosilver – acting on frequently used surfaces indoors and outdoors as well, are also available on the market. They do not contain organic ingredients and have a cleaning and disinfecting effect due to their silver ion content. Coatings applied to surfaces are transparent after drying, do not leave marks and are not harmful to the environment. As a result, a surface can also become self-cleaning and does not require UV-A light due to the silver ion content.

Killing bacteria with nanotechnology

A variety of tools and devices manufactured with a self-cleaning coating are already available. There are self-cleaning door handles created with several different technologies, or silver-ion-coated handles killing more than 99.99% of bacteria, though this has not yet been tested for viruses.

However, there are so-called HC3-coated handles that also use nanotechnology. They do not contain germicidal chemicals or silver ions, but a photocatalytic component that acts as a kind of catalyst. It also kills bacteria, organic waste and viruses quickly. HC3 is extremely durable, so the use of handles and other devices with such a surface is strongly recommended in, for example, healthcare facilities, nursing homes or nurseries.
