Silver nanoparticles (AgNPs) exhibit excellent antibacterial effects against both Gram-positive and Gram-negative bacteria. They represent a possible way to combat bacteria resistant to conventional antibiotic treatment. Over time, bacteria also become resistant to AgNPs. One solution is to modify the AgNP surface with various simple or more complex biomolecules with antibacterial activity. Such modifications can be achieved using so-called green synthesis. The green synthesis of AgNPs is based, for example, on the use of plant extracts as reducing agents. The AgNPs obtained have biomolecules derived from the extract bound to their surface. The aim of this work was to identify other plant species with a high content of secondary metabolites with the potential antibacterial activity that would make them suitable for green synthesis. A large number of plants occurring in tropical areas of Vietnam contain a lot of hitherto unspecified substances with the potential antibacterial effect. Nanoparticles prepared using extracts of harvested plants were characterized by physical and biochemical methods. Silver nanoparticles with the modified surface can be used to combat resistant bacteria.Keywords: Ethnobotany, biochemical analysis, antioxidant activity
