Summary
Chestnut shell extract effectively synthesized silver nanoparticles (AgNPs) with antimicrobial properties. These eco-friendly AgNPs show significant inhibitory effects against common bacteria and fungi.
Area of Science:
- Materials Science
- Nanotechnology
- Environmental Science
Background:
- Chestnut shells represent agricultural waste, posing environmental disposal challenges.
- Developing sustainable methods for waste utilization is crucial for environmental remediation.
Purpose of the Study:
- To synthesize monodisperse crystalline silver nanoparticles (AgNPs) using chestnut shell extract.
- To evaluate the antimicrobial efficacy of these synthesized AgNPs.
Main Methods:
- Hydrothermal synthesis utilizing chestnut shell extract as a reducing and stabilizing agent.
- Characterization using UV-Vis spectrophotometry, TEM, FTIR, XPS, and XRD.
- Antimicrobial activity testing against *Escherichia coli*, *Staphylococcus aureus*, and *Candida albicans*.
Main Results:
- Spherical AgNPs with a face-centered cubic crystal structure were successfully synthesized.
- AgNPs demonstrated significant antimicrobial activity against tested bacteria and fungi.
- Low minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) values were recorded.
Conclusions:
- Chestnut shell extract is an effective and sustainable precursor for AgNP synthesis.
- Functionalized AgNPs exhibit potent antimicrobial properties, offering a viable eco-friendly solution.
- This approach addresses agricultural waste management and provides an efficient antimicrobial agent.
