In the last decade, researchers were developing different types of nanoparticles and exploring more and more applications that made this area of research so promising and very active. Actually, many techniques can be followed in order to prepare nanoparticles. Usually either physical or chemical methodologies were applied. Nowadays, biological methods are very fast growing, moving the synthesis of nanoparticles towards more safe and eco-friendly way of production in addition of being cost effective. Although the chemical methods were used in majority of researches, they had many drawbacks; toxic chemicals are usually used, high cost of reagents, and multi-steps preparation methods
