Nanotechnology is a multidisciplinary and convergent area defined by European Commission as a Key Enabling Technology, representing one of the basic areas for the future employment growth, research, and technological innovation. Nanomaterials are probably the largest segment of this area, and noble metal nanoparticles (mNPs) are undoubtedly one of the main classes investigated and used so far. The common methods used for mNPs preparation are colloid-chemical approaches that involve the reduction of metal salts using diverse reducing agents. However, most of the reducing agents present environmental risks and human toxicity. To change this scenario, researchers started to study green solutions to minimize or eliminate the use of these harmful chemicals. These approaches comprise the use of different microorganisms, plants or plant extracts. The use of plant extracts presented several advantages due to their high diversity and abundance, simplicity, and cost-effectiveness. Moreover, the presence of plant metabolites at mNPs surface can also contribute to their biocompatibility and lower cytotoxicity as well as increasing efficiency.

Although green synthesis isn’t a new topic, its huge potential is undeniable, verified by the exponential growth of publications. However, almost all published works mainly focus the use of distinct plants extracts and few studies involve the real understanding of the formation mechanisms, not presenting in this way real relevant contributions. Furthermore, it is still necessary to establish specific routes to obtain a well-defined size, morphology, and monodispersity in order to find design scalable processes as well as to show new studies demonstrating the possibility of using these bionanostructures in the development of new and innovative functional nanocomposite materials.

In this sense, this special issue will attempt to respond to some of these gaps presenting novel studies in the field.

Scope of the issue
Novel and emerging insights into the synthesis and new developments in the understanding of the biosynthetic processes and study of innovative applications by themselves or used in nanocomposite materials.
