Green Synthesis of Silver Nanoparticles Exhibits Antimicrobial Potential

Strategic Insights

— 1 min read

Researchers from the Federal University Rio Grande, in Rio Grande, Brazil, have made a breakthrough discovery in the field of green synthesis. By using biomass from black soldier larvae (* * Hermetia illucens* * ), they have successfully synthesized silver nanoparticles (AgNPs) that exhibit antimicrobial properties. The study, published in the journal Microorganisms, demonstrates that these nanoparticles can reduce bacterial growth in vitro and protect the nematode * * Caenorhabditis elegans* * from infection by * * Pseudomonas aeruginosa* *.

Key Takeaways:

  • Researchers from the Federal University Rio Grande used green synthesis from black soldier larvae biomass to produce silver nanoparticles (AgNPs) that exhibited antimicrobial properties.
  • The study demonstrated that AgNPs produced from * * H. illucens* * biomass can reduce bacterial growth in vitro and protect * * C. elegans* * from infection by * * P. aeruginosa* *.
  • The results showed that AgNPs from green synthesis are less harmful to the environment while maintaining their antimicrobial potential.
  • The study was funded by the National Council For Scientific And Technological Development, Foundation of The State of Rio Grande Do Sul, and Inova Clusters Tecnologicos.
  • The research was led by Alinne Ayech, with additional authors including Gabriela Hollmann, Robson M. Marreiro Gomes, Belisa A. Rodrigues, Vanessa K. Engers, Rafael S. Goncalves, Sandro Daniel Nornberg, Daniela F. Ramos, Karine Rigon Zimmer, and Jose M. Monserrat.

Statistics:

  • The AgNPs produced from * * H. illucens* * biomass had an average size of 8 ± 3.5 nm.
  • The AgNPs exhibitted absorption spectrum peaks around 400 nm.
  • The study showed 100% mortality of * * P. aeruginosa* * -infected worms without treatment with AgNPs within 3 days.
  • The AgNPs-treated worms survived until the end of the experiment, with no statistical differences compared to non-infected worms of the control group.
