In this study, silver nanoparticles (Ag NPs) were decorated on the surface of magnetic nanoparticles in an eco-friendly pathway applying Mentha extract as reducing/stabilizing agent. The morphological and physicochemical features of the prepared Ag/Fe3O4nanocomposite were determined using several advanced techniques. Hence, our protocol is green and advantageous in terms of- i) biochemical modified biocompatible nanocomposite; ii) nanomaterial providing high surface area and larger number reactive sites; iii) very simplistic synthetic procedure; vi) very low load of metal in the composite and v) high yield in short time. In the medicinal part, the anticancer properties of Ag/Fe3O4 nanocomposite against lung cancer cell lines were determined. The free radical for the antioxidant effects was DPPH. The IC50 of Ag/Fe3O4 nanocomposite was 200 µg/ml in the antioxidant test. The IC50 of the Ag/Fe3O4 nanocomposite were 183, 176, 169, and 125 µg/mL against lung cancer (NCI-H661, NCI-H1975, NCI-H1573, and NCI-H1563) cell lines, respectively. In addition, the current study offer that Ag/Fe3O4 nanocomposite could be a new potential adjuvant chemopreventive and chemotherapeutic agent against cytotoxic cells.
