Özet
This study aims to synthesize silver nanoparticles (Br-AgNPs) using the extract of the unique black rose (Rosa x damascena Mill.) grown in Halfeti, Şanlıurfa, Türkiye, through an environmentally friendly green chemistry approach, and to evaluate their antioxidant performance. The plant-mediated synthesis method offers a sustainable and non-toxic alternative by enabling both reduction and stabilization through naturally occurring biomolecules. The formation of Br-AgNPs was confirmed by a characteristic surface plasmon resonance band at approximately 440 nm in UV–Vis spectroscopy, while SEM analyses revealed relatively uniform nanoparticles with sizes between 45 and 52 nm. To assess their biological potential, DPPH•, ABTS•⁺, and reducing power (FRAP) assays were conducted. As can be seen from the figure presented within this abstract, Br-AgNPs exhibited notably strong radical-scavenging and electron-donating capacities, particularly against the ABTS•⁺ radical. Results were reported as mean ± SD from three independent replicates, and comparisons with standard antioxidants (Trolox, BHT, BHA) further confirmed the remarkable antioxidant performance of the nanoparticles. These findings demonstrate that the green synthesis route utilizing Halfeti black rose extract is an effective and sustainable method for producing biocompatible silver nanoparticles with significant antioxidant activity.
