Scientists Invented ‘Nano Disinfectant’ in Water Shape

US researchers; He invented nano-sized disinfectant that will protect the air, our hands, our food from microbes. One of the most important features of this disinfectant is ‘artificial water’.

Harvard T.H. Researchers from Chan Faculty of Public Health have produced a new disinfectant that can be used to combat infectious diseases. This new disinfectant; It will clean the air we breathe, our nutrients, our hands, and everything that can make us sick by having microbes.

Researchers produced small and aerosolized nano water droplets on a platform built with nanotechnology tools. These nano droplets contain non-toxic disinfectants that can clean the desired location.

Inspired by nature in the new disinfectant:
Philip Demokritou, who is an associate professor in the field of aerosol physics, reminds us that respiratory and nutrient-borne diseases are still alive, reminding that 1 million people die every year due to respiratory-borne diseases and 500,000 due to food-borne diseases.

Demokritou, which draws attention to the importance of hand cleaning; says that for this we use chemicals such as antiseptics, alcohol, triclosan and chlorhexidine. However, the scientist says that there are studies showing that these chemicals increase antibiotic resistance, and some people are also sensitive to frequent contact with water and chemicals.

Emphasizing that they have been working on nanotechnology-based solutions for several years, Demokritou notes that with the new research, they can turn water into nanoparticles of artificial water and disinfect the surfaces and air with the antimicrobial components in them.

‘Artificial water but still water’
According to Demokritou, the setup is very simple. The 12 volt electro spray and ionization turns the water into nano aerosole, and these nano particles hang in the air. These nano water droplets have small dimensions and reactive oxygen derivatives. These are hydroxyl radicals and organic peroxides that our cells use to fight pathogens.

These nanoparticles, by their design, also carry an electrical charge, so surface energy increases and evaporation decreases. This means that these nanoparticles can hang in the air for hours. When the electric charge disappears, the particles become water vapor and disappear.

Demokritou emphasizes that they use nature-inspired disinfectants, but their volume corresponds to only 1 percent or 2 percent of the nano droplets. The rest of the nano-water particles is still water.
