Antimicrobial Activity of Silver Nanoparticles Synthesized using Marine Brown Seaweed Spatoglossum asperum against Oral Pathogens

Background: Green synthesis of nanoparticles using plant extract, bacteria, fungi and enzymes are ecofriendly and cost effective which do not need high pressure, energy, temperature and toxic chemicals for its synthesis protocol.

Materials and Method: In this report, we used the extract of marine brown algae Spatoglossum asperum to synthesize silver nanoparticles and were characterized using UV-visible spectrophotometer, TEM, XRD and FTIR and were also tested for their antimicrobial activity.

Results: These biosynthesized silver nanoparticles exhibited potent antimicrobial activity against oral pathogens namely, Streptococcus mutans, Enterococcus faecalis, Pseudomonas aeruginosa and Candida albicans and can be developed as a novel medicine against pathogenic oral diseases.

Conclusion: With increasing demand in advancements in diagnosis and treatment modalities, green synthesis of silver nanoparticles using marine brown algae Spatoglossum asperum has potent antimicrobial action have wider applications in dentistry.
