Is There Any Correlation Between Green Synthesis Parameters and the Properties of Obtained Selenium Nanoparticles?

Area of Science:

• Nanotechnology
• Materials Science
• Green Chemistry

Background:

• Selenium nanoparticles (SeNPs) possess significant potential for biomedical applications.
• Green synthesis methods for SeNPs are gaining prominence due to their environmental benefits.
• Understanding synthesis conditions is crucial for tailoring SeNP properties.

Purpose of the Study:

• To investigate the impact of green synthesis conditions on selenium nanoparticle properties.
• To explore the use of eight different medicinal herb extracts for SeNP synthesis.
• To correlate synthesis parameters (reagent ratio, temperature) with SeNP characteristics.

Main Methods:

• Green synthesis of SeNPs using extracts from eight medicinal herbs.
• Systematic variation of reagent ratios and reaction temperatures.
• Characterization of SeNPs using zeta potential measurements.
• Analysis of correlations between synthesis conditions and nanoparticle size.

Main Results:

• All synthesized SeNPs exhibited high stability, indicated by negative zeta potential values (-11.8 to -29.4 mV).
• The strongest correlation between SeNP size and reagent ratio was observed at elevated temperatures (R=0.914) compared to room temperature (R=0.681).
• The smallest SeNPs were consistently produced using a 1:1 reagent ratio across different conditions.

Conclusions:

• Green synthesis using medicinal herbs provides a viable route to stable selenium nanoparticles.
• Reagent ratio and temperature are critical factors influencing SeNP size during green synthesis.
• A 1:1 reagent ratio is optimal for achieving smaller selenium nanoparticles via this method.
