Özet

Silver nanoparticles (AgNPs) are attracting attention and gaining popularity every day due to their unique physicochemical properties and wide range of applications. Recently, green synthesis approaches have emerged as sustainable and environmentally friendly alternatives to conventional chemical synthesis methods. In this study, oak acorn extract was selected as a natural reducing and stabilizing agent due to its rich phenolic, flavonoid, tannin, and other bioactive compound content. These compounds provide strong antioxidant and reducing properties, enabling efficient green synthesis of silver nanoparticles. In addition, oak acorns are abundant and renewable biomass resources, making them a sustainable choice for nanoparticle synthesis. AgNPs were synthesized using an eco-friendly green synthesis method based on oak acorn shell extract as a natural reducing and stabilizing agent. The plant extract was prepared via aqueous extraction. The extraction process was carried out with maceration and AgNP synthesis was carried out by reacting the extract with silver nitrate under controlled experimental conditions. Reaction parameters were selected according to literature data to promote effective nanoparticle formation. The formation of AgNPs was confirmed by UV–Visible spectroscopy, where a characteristic surface plasmon resonance (SPR) peak was observed in the typical wavelength range at ~ 450 nm for AgNPs. Fourier Transform Infrared (FT-IR) spectroscopy analysis revealed the presence of functional groups associated with phenolic compounds in the oak acorn shell extract, indicating their role in the reduction of silver ions and stabilization of the synthesized nanoparticles. AgNPs were used to modify the carbon paste electrode (CPE) and increase its conductivity. The effect of changes in response currents with increased conductivity was determined by H₂O₂ sensitivity. Overall, the results demonstrate that oak acorn shell extract can be effectively utilized for the green synthesis of AgNPs. This sustainable, rapid, and environmentally friendly approach offers a promising alternative to chemical synthesis methods and provides significant potential for designing biosensors for various analyte determinations and other future applications where AgNPs will be used.
