Abstract
Nanotechnology, the invention and creation of particles with sizes up to100 nm, has emerged as a primary field of modern research and were especially important in electronics and medicine. The creation of the smallest unit at the atomic scale of components to achieve large structures with the new organization at the molecular level is the goal of nanotechnology.
Considerable efforts to manipulate environmental friendly methods for the synthesis of noble metal nanoparticles have been conducted. These are usually accomplished by the utilization of plant leaves or fruit extracts and bio-organisms. Moreover, green methods have the privilege of being fast and efficient leading to the production of crystalline nanoparticles.
A diversity of shapes as spheres, rods, prisms, plates, needles, leafs or dendrites are thus achieved. Using of microwave heating significantly decreases response times, increases product yields and improves product’s purities by minimizing unwanted side reactions compared to traditional methods. Its enhanced chemistry depends on the perfect heating of materials by “microwave dielectric heating” effects.
Compared to traditional courses, microwave assisted synthesis is faster, leading to particles with smaller size. A green approach was manipulated, in the present work, to produce extracts from two different plant sources applying microwave energy to achieve mono-dispersed silver nanoparticles (AgNPs). Extracts were obtained from an Asian nut: almond and a particular traditional Egyptian fruit: the blackberry. Each extract was used separately for the synthesis of AgNPs using the microwave irradiation for several exposure periods but at a constant power. In addition to that hydroxyapatite (HA) which naturally exists in bone structure was prepared and silver nanoparticles added to it as anti bacterial agent for using in some medical applications.
