Many methods aiming at the formation of silver nanoparticles, including the green ones, make use of an organic molecule. The latter interacts with the particles and provides them with stability against oxidation and agglomeration, or it can even act as a matrix only. In this sense, polymer molecules have been widely employed because their long chain offers many binding sites in which nanoparticles can be stabilized [14]. Moreover, natural polymers are extremely important because many of them are biocompatible and non toxic. Among such biomolecules are sucrose [15], maltose [15], chitosan [16], arabic gum [17] and plant extracts such as the ones obtained from Jatropha curcas [18], Murraya Koenigii [19] and Mangifera indica [20]. More specifically, the natural rubber latex (NRL) extracted from Hevea brasiliensis, a native tree from the Amazon forest, arises as a possible biomaterial for use in synthesis of nanoparticles [21].
