Synthesis of silver flower-like particles and evaluation of their antibacterial activity

Abstract

Ag nanoflowers (AgNFs) were synthesized using theHamelia patensplant extract, and their antibacterial properties were evaluated against Escherichia ColiandStaphylococcus aureus. SEM analysis showed that the size of AgNFs was 2 μm, and they were made up of randomly oriented nanosheets that were 100 nm thick. The petals grew in an anisotropic form on the Ag fcc lattice. The synthesis process involved using glycoside compounds in the plant extract as reducing agents, confirmed by FT-IR and HNMR techniques. The AgNFs exhibited antibacterial activity against both bacteria strains.
