Green Synthesis of Luminescent Silver Nanoparticles Using Annona reticulata Fruit: Evaluation of Biological and Environmental Applications

Green metal nanoparticles are used as building blocks for nanomedicine because they are safe, cheap, and last a long time. Natural products combined with silver nanoparticles (AgNPs) were identified by researchers to have applications in medicine and the environment. Our study focused on creating Annona reticulata fruit-based luminescent silver nanoparticles (ARF-AgNPs) and their antioxidant, antibacterial, and photocatalytic potential. The A. reticulata fruit-based luminescent silver nanoparticles (ARF-AgNPs) were characterized by UV-visible spectroscopy, Fourier transform infrared (FT-IR) spectroscopy, X-ray diffraction (XRD), and field emission scanning electron microscopy with energy dispersive X-ray spectroscopy (FESEM-EDX). The antioxidant action of ARF-AgNPs against DPPH radicals was found to show that at 500 μg/mL, their activity level ranged from up to 80.21 ± 0.91%. As bacterial pathogens, Staphylococcus aureus and Pseudomonas aeruginosa were used to assess the bactericidal efficacy of ARF-AgNPs. Furthermore, capable of accelerating the malachite green (MG) dye responses were the green ARF-AgNPs. Therefore, these findings suggest a feasible method for producing ARF-AgNPs from A. reticulata fruit rind, which can be used in several chemical and medicinal applications.
