The extensive use of nanocomposites in the field of medicine and pharmaceuticals stems from their physicochemical properties and due to their potential therapeutic application. Further, nanopharmaceutics take a significant role in designing smart drug-release and controlled drug delivery, where the drug is efficiently reached towards the target sites within a predictable and limited timescale. The scope of present research work is to synthesis an ecofriendly silver nanocomposite (Ag/Ag 2 O) by using alcoholic fruit extract of Pheonix slyvestris and its efficiency was evaluated for anticancer activity. PXRD results and HRTEM images confirmed that Ag/Ag 2 O was crystalline in nature with diverse morphology and possessed an average particle size of 23–50 nm. Surface plasmon resonance of Ag/Ag 2 O was observed at 465–500 nm in UV-DRS. The PL spectrum of Ag/Ag 2 O NPs shows two asymmetric peaks confirming the formation of Ag/Ag 2 O heterocomposite. The cytotoxicity study Ag/Ag 2 Osynthesized via green chemistry was performed using the MTT (3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyltetrazolium bromide) assay against breast cancer cell line (MCF7) with an IC 50 21.61 μg/mL. The results of the cytotoxicity tests showed a concentration dependent outcome against tumor cells and a correlation between dosage and effectiveness against tested cancer cell line. DFT studies revealed the sensing response of Ag/Ag 2 O composite towards doxorubicin drug confirmed by relative work function changes. Molecular docking and dynamics simulation resulted that the Ag/Ag 2 O illustrates to be an excellent lead molecule. In conclusion, the present research work demonstrated that Ag/Ag 2 O synthesized from alcoholic fruit extract of Pheonix slyvestris may be an impending remedial drug for breast cancer management.
