“…Synthesis of magnetic NPs represents the primary step towards the fabrication of desired composite materials. A comprehensive literature survey reveals that magnetic nanoparticles such as Fe 3 [59][60][61][62][63][64][65][66][67][68] Synthetic methodology employed while preparing magnetic nanoparticles is ascertained to have profound effect on the shape, size, morphology and surface chemistry of the resulting nanostructure which further escalates their utilization in diversified fields. Numerous preparative techniques such as co-precipitation, 69 solvothermal or hydrothermal, 70 thermal decomposition, 71 sonochemical, 72 sol-gel, 73 electrochemical, 74 microwave assisted, 75 bio-inspired (microbial and plant mediated) 76 and microemulsion 77 are very well described in several reviews documented in literature.…”
