The dynamic development of the world economy entails an increasing exchange of goods and population. This means that we are globally struggling with increasing levels of nosocomial infections. The increasing use of antimicrobial agents triggers the microorganisms’ immune system, which in turn contributes to the increasing amount of antibiotic-resistant microorganisms, making it necessary to control the development of unwanted microorganisms, including bacteria, especially those carried on the body and clothing. Currently, there is no unique method to combat the multiplication of microorganisms and eliminate threats to human health and life. For this reason, this article describes the possibilities of using graphene materials as a potential additive materials in fiber finishes as an antibacterial aspect in various areas of life. However, the literature does not explain the mechanisms behind the antibacterial properties of graphene, strongly limiting its textile application. The research is conducted using molecular dynamic simulations of interaction between graphene materials and murein. The obtained results suggest the electrostatic mechanism of blocking the growth and division of bacteria. Due to the physical interaction, bacterial cell becomes “trapped” without changing its growth parameters. This may lead to an increase of internal cell pressure, rupture of its wall and consequently its death.
