AB  - The development of eco-benign experimental procedures for the synthesis of 
      nanomaterials is a fundamental developing branch of green nanotechnology. In this 
      paper, green synthetic route was followed to synthesize novel 
      Au@Fe(2)O(3)nanocomposite using Citrus sinensis fruit extract as a reducing and 
      stabilizing agent. The as synthesized Au@Fe(2)O(3)nanocomposite was successfully 
      characterized by UV-visible spectroscopy, X-ray diffraction (XRD), Scanning 
      electron microscope (SEM), Energy-dispersive X-ray (EDX), Fourier transform 
      infrared (FT1R) spectrophotometry and Zeta potential. UV-vis spectroscopy showed 
      two SPR peaks for Fe(2)O(3) and coated Au at 290 and 520 nm respectively. XRD 
      confirmed the crystallinity of Au@Fe(2)O(3.) Au@Fe(2)O(3) nanocomposite showed 
      better antioxidant activity to effectively scavenge DPPH. The Au@Fe(2)O(3) has 
      been also tested for antibacterial activity which showed an effective 
      antibacterial activity against multi drug resistant E.coli and Bacillus subtilis. 
      Furthermore, Au@Fe(2)O(3) also demonstrated better photo catalytic activity for 
      methylene blue (MB) degradation. We proposed that the existence of organic acids 
      (citric acids) also played a significant role in the stabilization of 
      Au@Fe(2)O(3), and plant (Citrus sinensis Var Kozan yerly) containing such 
      component may be more effective for the green synthesis of Au@Fe(2)O(3) 
      nanocomposite. The findings of this study prove the overwhelming therapeutic and 
      photocatalytic potential of bio-inspired Au@Fe(2)O(3)nanocomposite which can be a 
      novel candidate for the effective remediation of microbes and toxic organic 
      pollutants.
