Due to the increase in research on nanotechnology, the need to produce and use materials with Nano metric dimensions has expanded significantly. The widespread use of nanoparticles in a wide range of different sciences (especially in the health and medical industries) makes it essential that these materials are free from harmful and polluting chemicals. Green nanotechnology can help minimize environmental concerns associated with the manufacture and use of nano-based materials and products. One aspect of this discussion is the use of microscopic organisms in nanotechnology, which can simultaneously solve the problems related to the synthesis of nanoparticles and their stabilization under mild conditions. Among microscopic organisms, bacteria have received more attention than other organisms due to their ease of work and the possibility of genetic manipulation. Another aspect of green nanotechnology is the use of enzymes in this technology. Some enzymes are nanometer-sized biocatalysts and have now found wide application in new fields such as pure chemical synthesis, removal of bio pollutants and in pharmaceuticals; however, the short life of enzymes has limited their use in this application. The use of plants as a sustainable and available source for the preparation of biocompatible nanoparticles has received much attention, and the advantages of this method include cheapness, non-toxicity, and the production of high-purity nanoparticles. In addition, nanoparticles produced in this way are more uniform in terms of particle size distribution and stability (have a homogeneous structure) than other methods. Lower cost, faster speed, large scale production and no threat to the environment are other advantages of using green technology. In recent years, the positive potential of producing various nanoparticles by biological methods with the help of bacteria, fungi and plants has been proven by various researches. In green nanotechnology, plant extracts are the most common materials for producing nanoparticles. These extracts can usually be extracted from plants by very simple methods (such as boiling). The ease of synthesis in preparing nanomaterials with green plant synthesis technology (phytosynthesis) is a very positive and practical aspect of modern nanotechnology for producing nanomaterials in various industries, especially medicine and pharmaceuticals.
