Black phosphorus killed 99% of dangerous bacteria and fungi
Australian scientists have identified a substance that can effectively destroy fungi and bacteria. It turned out to be black phosphorus, according to ACS Applied Materials & Interfaces.
Black phosphorus is the most inert form. Representatives of the Royal Institute of Technology of Melbourne tested how it works on five of the most common types of bacteria, including staphylococcus, and five widows of fungi.
Experiments have shown that on surfaces covered with a layer of black phosphorus, about 99% of pathogenic microorganisms die within two hours. To achieve the desired effect, only a few nanograms of the substance were enough. The authors of the scientific work suggested that the reason lies in the active oxidation of cellular structures by phosphorus.
Importantly, black phosphorus did not adversely affect either laboratory mice or human cell cultures. The coating itself disintegrates completely within 24 hours without additional treatment.
Scientists have come to the conclusion that the use of black phosphorus has great prospects. It is able to effectively fight harmful bacteria, but it does not accumulate in the human body and does not require additional disposal.
Earlier it was reported that microbes unknown to science were found on the ISS. Scientists have conducted genetic analysis of the strains.
