Abstract
The present study demonstrates the production of silver nanoparticles (SNPs) utilizing
an aqueous extract from the stem of Mangifera indica and their application as an
antimicrobial agent against diverse pathogenic microorganisms. The presence of a
dark brown colour visually supported SNP biosynthesis, which was also confirmed
by UV spectra at 450 nm. FE-SEM (Field Emission Electron Scanning Electron Microscopy)
examinations revealed the nanoparticles' spherical to oval shape, while EDX (Energy-Dispersive
X-ray) research proved their elemental makeup. XRD research revealed that SSNPs
(Stem SNPs) have a face-centred cubic crystalline structure with an average size
of 10 nm. FT-IR research demonstrated that the bio-functional groups included in
the plant extract stimulate the production of SNPs while also promoting the capping
and stabilization of the SNPs. The phytochemical examination revealed the presence
of bioactive compounds. The SSNPs had more antibacterial activity than antifungal
activity. A single-factor ANOVA was used for statistical analysis and p < 0.05 was
considered statistically significant.
The study's findings indicate that many naturally occurring bioactive chemicals
in plant extracts may be usefully employed in nanoparticle-making. In contrast to
traditional antibiotics, this study demonstrated an effective, practical and repeatable
approach for manufacturing inexpensive, environmentally benign and long-lasting
plant-mediated SNPs and their use as powerful antimicrobial agents against pathogenic
microorganisms.
