Abstract
The green synthesis of nanomaterials is nowadays gaining great attention owing to several beneficial aspects in terms of the low toxicity of reagents and by-products, low damage to the health and the environment, sustainability of energy savings and rational use of natural resources. The intrinsic complexity offered by the biological sources (plants, microorganisms, animal products) and the conditions applied in the synthetic procedures forms various nanomaterials with different sizes, morphologies and surface properties that strongly determine their functionality and applications. A deep understanding of the role of biological components, the mechanism of nanostructure formation and growth, and the effects of green synthesis conditions is of paramount importance to achieving the desired nanomaterial for the required application. In this context, this review aims to provide an overview of the structural and functional complexity of nanomaterials achieved by using green synthesis procedures, with a special focus on the role of biological sources and parameters in controlling the complexity and benefit of nanomaterial applications.
Keywords: green synthesis, nanoparticles, anisotropic structures, nanomaterials, biogenic synthesis, fractal structures.
