The book entitled "Modern Ayurvedic method: iron oxide nanoparticles" deals with synthesis and characterization of iron oxide nanoparticles by novel route and examining chlorophyll activity on Solanum lycopersicum seeds. The crystallite size decreases with increase in subsequent quenching by herbal juices in the purification steps. From X-ray diffraction it is concluded that phase transformation from α to γ phase,which is further confirmed by UV-Visible Spectroscopy and VSM studies that the sample exhibit super paramagnetism.TEM analysis revealed that the obtained nanoparticles are cubic in nature,which is compared with the XRD analysis. The method is successful and exhibit fruitful results on chlorophyll examination.
