What is it about?
The present experiment reports the eco-friendly approach of bio-fabrication of Sr-Ag nanoparticles from AgNO3 using the aqueous extract of Sr. The implemented method is well suited with the nanotechnology and its application in the biomedical field. Aqueous extract of the Sansevieria roxburghiana serves the dual functional molecules which act as a reducing and stabilizing agent for the synthesis of stable Sr-Ag nanoparticles. The UV–Vis spectral study has confirmed the reduction of Ag+ ions and formation of Sr-Ag nanoparticles at 429 nm on 24 h of reaction time. X-ray the analysis revealed the basic crystalline nature and face centred cubic (fcc) structure of Sr-Ag nanoparticles. DLS and SEM studies of the prepared Sr-Ag nanoparticles confirmed the size and shape. Finally, the anti-bacterial studies gave the a significant zone of inhibition for both Gram-negative and Gram-positive strains.

Why is it important?
Antibacterial activity of bio-synthesized Sr—Sr-Ag nanoparticles show effective inhibition against human pathogens including, Bacillus subtilis (ATCC 6633) and Escherichia coli (ATCC 25922). Thus, the significant outcomes of this study would help to formulate value-added herbal-based nanomaterials in biomedical and nanotechnology industries.
Perspectives
The present study focused on the fabrication, demonstration and application of silver nanoparticles (Ag-nanoparticles), which can be used in biomedical research and ecological cleaning applications.
