研究目的
To develop an environmentally friendly process for the synthesis of silver nanoparticles (AgNPs) using aqueous extract of S. bryopteris and to study their antimicrobial and photocatalytic activities.
研究成果
The biosynthesized AgNPs demonstrated significant antimicrobial activity against gram-positive bacteria and effective photocatalytic degradation of dyes under solar light, suggesting their potential as eco-friendly alternatives for antimicrobial and environmental remediation applications.
研究不足
The study did not explore the mechanism of nanoparticle formation in detail or the long-term stability of the synthesized AgNPs under various environmental conditions.
1：Experimental Design and Method Selection:
The study utilized a green synthesis approach for AgNPs using S. bryopteris plant extract as both reducing and stabilizing agents.
2：Sample Selection and Data Sources:
S. bryopteris was procured from a local market, and silver nitrate was used as the precursor for AgNPs synthesis.
3：List of Experimental Equipment and Materials:
UV-vis spectrophotometer, XRD, FT-IR spectrometer, TEM, and other standard laboratory equipment were used.
4：Experimental Procedures and Operational Workflow:
The synthesis involved mixing plant extract with silver nitrate solution, followed by characterization and testing for antimicrobial and photocatalytic activities.
5：Data Analysis Methods:
UV-vis spectroscopy for SPR analysis, XRD for phase identification, TEM for morphology and size determination, and disc diffusion method for antimicrobial activity.
