ABSTRACT

Silver nanoparticles (AgNPs) have been extensively explored due to their varied biological properties. Annona muricata. L leaf extract-derived silver nanoparticles (AM-AgNPs) were synthesized and characterized using UV–Visible spectroscopy, ATR-FTIR spectroscopy, and Scanning Electron Microscopy (SEM). A characteristic surface plasmon resonance peak at 440 nm was detected in the UV–Visible absorption spectrum, confirming AgNPs formation. SEM analysis revealed particle sizes ranging from 350 to 650 nm, while ATR-FTIR identified functional groups involved in the reduction and capping of silver ions, providing insights into surface morphology and stabilization. Phytochemical profiling by LC–MS and DPPH study revealed a 25% enhancement in antioxidant activity in the AM-AgNPs compared to A. muricata leaf (AML) extract alone. In addition, a sustained release of 77.3% over 24 hr. established effective entrapment and prolonged delivery potential. The entrapment efficiency of phytochemicals within AM-AgNPs was found to be in the range of 74.23–81.09%, representing strong phytochemical association with the nanoparticles. Cytotoxicity evaluated by MTT assay using MCF-7 breast cancer cell lines showed concentration-dependent growth inhibition, with an IC₅₀ value of 74.51 µg/mL.
