Overview

Experimental review reveals optimal plant extract concentration produces stable silver nanoparticles, highlighting the critical role of reaction parameters in green nanotechnology.

Key Points

To review the effects of pH, temperature, and reagent concentration on green silver nanoparticle synthesis and experimentally determine the optimal plant extract concentration using Astrocaryum aculeatum.
Critically reviewed key physicochemical parameters (pH, temperature, reagent concentration) governing silver nanoparticle (AgNP) formation, morphology, and stability.
Synthesized AgNPs across three independent batches using Astrocaryum aculeatum extract at concentrations of 10, 15, 20, and 30 g L⁻¹.
Evaluated particle characteristics using UV–Vis spectroscopy, dynamic light scattering (DLS), polydispersity index (PDI), and nanoparticle tracking analysis (NTA).
Surface plasmon resonance (SPR) peaks appeared at 406.3 ± 3.2 nm (10 g L⁻¹), 410.0 ± 2.0 nm (15 g L⁻¹), and 407.0 ± 1.0 nm (20 g L⁻¹), whereas 30 g L⁻¹ showed no resolved SPR maximum.
Increasing extract concentration from 15 to 30 g L⁻¹ increased mean hydrodynamic diameter from 220.0 ± 19.0 nm to 786.3 ± 108.8 nm and PDI from 0.338 ± 0.015 to 0.939 ± 0.050 [F(3,8) = 160.50, p < 0.001].
NTA identified 15 g L⁻¹ as the optimal concentration, achieving the highest particle-number yield at (5.41 ± 0.18) × 10¹⁰ particles mL⁻¹.
