Russian specialists from the "Institute of Cytology and Genetics SB RAS" (ICiG SB RAS) have proposed a new technology for creating nanomaterials with antibacterial properties.
The characteristics of the materials may depend on the chemical composition and/or structure. Specialists from the Institute of Cytology and Genetics of the Siberian Branch of the Russian Academy of Sciences have found a way to easily obtain vertically oriented lamellar nanoparticles at a relatively low temperature.
The vertical orientation makes it possible to place significantly more nanoparticles on one area of ββthe substrate. And this, in turn, opens the way to changing the properties of the final product.
βIn practice, this method was tested on hexagonal boron nitride (h-BN), a material similar in structure to graphite. As a result of the change in the orientation of the h-BN nanoparticles, the material actually acquired new properties, in particular, according to the creators, antibacterial,β the publication of the Institute of Cytology and Genetics of the Siberian Branch of the Russian Academy of Sciences says.
Studies show that upon contact with vertically oriented nanoparticles, more than half of the bacteria die after an hour of interaction. Apparently, this effect is associated with mechanical damage to the bacterial cell membrane upon contact with nanoparticles.
The new technology could come in handy when applying antibacterial coatings to medical instruments and other surfaces. In addition, in the future, the proposed technique may find application in other areas.
