“…2 shows the XRD pattern of the synthesized Ag NPs, with four different peaks at 2q ¼ 38.43 , 44.57 , 64.75 and 77.65 corresponding to the Bragg's reflection from the (111), (200), (220) and (311) planes respectively. The XRD pattern of the Ag NPs, which belongs to the face centered cubic structure with lattice parameters, [29]. The observed data agree well with the experimental values (ICDD 04e0783).…”

“…SERS has become a prominent tool for monitoring the changes in the chemical nature of the molecule adsorbed on silver nanoparticles (Ag NPs). Silver is the most universal substrate due to its broad plasmon resonance in the visible region, high stability and easy preparation [6]. Silver is known to scatter light better than the other noble metal like gold, copper and platinum.…”

“…Silver is known to scatter light better than the other noble metal like gold, copper and platinum. Ag NPs have been widely studied due to their useful physical and chemical properties and as the substrates for SERS [7]. Ag NPs, generally associated with their anti-bacterial properties, have also been incessantly gaining momentum recently.…”

“…Even though silver and silver‐based materials has considerable medicinal properties, their toxicity in the living system was still found to be objectionable. The medicinal property of silver can be further improved by size reduction of bulk counterparts to micro and nanoscale levels ,. It has been reported that at nanoscale range silver shows superior chemical, physical and optical properties with good surface functionality for the targeted therapeutic application .…”

The modern biomedical nanotechnology necessitates functionalized nanoparticles for targeted action on diseased cells with excellent physico chemical properties. The present study revealed the potential of fabricating juglone silver nano framework for selective cancer cell death by altering the redox states in the cancer cell and selectively inhibiting its growth and proliferation. Conjugation of Juglone with silver nanoparticle reduced the toxicity against normal cells and specifically only inhibited the proliferation of cancer cells. The mechanism of the selective cytotoxic and apoptotic effect on cancer cell was due to down‐regulation of NADPH oxidase 4, Hypoxia‐inducible factor 1α and subdued Pyruvate kinase M2 by arresting Wnt/β catenin signaling through ROS dependent caspase‐3 pathway. Collectively, our findings epitomized that functionalization of nanoparticle gives up a new perspective for adding‐in and tuning the therapeutic values by altering the redox states in cancer cells. Implications of this study opens up a new horizon in modern biomedicine for tuning therapeutic entities to meet the needs of practical applications in complex biological systems.
