Analysis of plant extract for the synthesis of nanoparticles

The green chemistry routes are used to prepare nanoparticles. One of the methods is used of plant extract. Phytochemicals that obtained in the extract of some selected medicinal plants contain reducing or oxidizing molecules along with many traces elements. These wide ranges of phytochemicals present in the plant extract can be used as capping agent or to reduce metal ions or metal oxides to its nanoparticles or nanocomposites such as Ag, Au, Ni, SnO₂ and Fe₃O₄ etc. Examples of commonly used medicinal plants are Neem (Azadirachta indica) and Tulsi (Ocimum tenuiflorum), Gotu kola (Centella Asiatica), Brihati (Solanum Indicum), Skunkvine (Paederia Foetida) and Lemon plant etc. Not only these, many plants which are in Rhizome family also contain reducing or oxidizing molecules along with many traces elements which also able to work as capping agent to get of nanoparticles. However, analysis of trace elements and compounds extracted from plants (leaves, shoot, flower, seeds, rhizomes) are necessary so that which are responsible for the formation of nanoparticles and the reduction of agglomeration among particles. In order to perform experiment to the better ways, it needs nuclear reactor utilizations. The following techniques are needed: 1. Neutron activation analysis (NAA) for trace elements analysis. Small angle neutron scattering for shape and size determination
