Silver nanoparticles were produced using an efficient, eco-friendly, and biosynthetic
method involving leaf extracts from Malva Sylvestris and Lantana Camara. The costeffective
and eco-friendly process of synthesizing silver nanoparticles using plant
extracts has attracted considerable interest. Silver nanoparticles were synthesized in
this study by combining silver nitrate solution with aqueous and ethanolic leaf extracts,
resulting in the reduction of Ag+ ions and the production of silver nanoparticles. The
silver nanoparticles produced through biological synthesis were analyzed using several
techniques. UV-Vis spectroscopy was used to detect the creation of silver
nanoparticles, showing unique UV absorption peaks between 300 to 600 nm. The
face-centered cubic structure of synthesized crystalline silver nanoparticles was
confirmed using X-ray diffraction patterns, while SEM was utilized to analyze the
morphology and size of the silver nanoparticles. Zeta potential is used to measure the
surface charge and potential stability of silver nanoparticles in solution. To identify
the functional groups responsible for NPs stabilization Fourier, transform infrared
spectroscopy (FTIR) was used. These characterizations provide a thorough
understanding of the physicochemical properties of biosynthesized silver
nanoparticles. Their antibacterial and catalytic activities demonstrate their potential for
diverse biomedical and environmental uses. The manufacture of silver nanoparticles
by using leaf extracts from Malva Sylvestris and Lantana Camara is practical,
environmentally beneficial, and serves as an alternative to conventional methods.
The synthesized silver nanoparticles preparations demonstrate potential for use as
broad-spectrum antibacterial agents and catalysts. This research contributes to the
increasing knowledge on green production techniques for nanoparticles and their
various uses
