dc.description.abstractMetal nanoparticles have proven to have antimicrobial properties, but the chemical methods used in their production involve use harzodous chemicals. In this study, ecofriendly method was used for the synthesis of silver nanoparticles using B. micrantha. The reaction was done over ultrasonic bath. Formation of the nanoparticles was monitored by use of UV-VIS spectrophotometer and absorption peak at λmax 431 nm was obtained. EDX analysis showed the nanoparticles were pure silver. HRTEM analysis showed the nanoparticles had non uniform surface and were spherical with an average size of 16.07±3.192 nm. SAED showed distinct shiny spots, confirming crystallinity of the nanoparticles. FTIR analysis indicated the presence of biomolecules capping the nanoparticles. The silver nanoparticles inhibited growth of E.coli and S. aureus. The study contributes in designing novel methods geared towards development of drugs to combat pathogens by use of silver nanoparticles.en_US
