Nanomaterials have distinctive properties compared to the bulk form. Among nanomaterials, nanometals played a crucial role in various fields such as environmental science, drug delivery, biomedicine, and catalysis. Recently, nanometals synthesized on organic materials including polymers, small molecules, and natural compounds have been widely studied and developed for numerous advanced applications.

The controllable and cost-effective synthesis of nanometals requires cutting-edge technologies to develop next-generation devices with many potential applications. Green approaches for nanometallic production also provide additional advantages for the applicability of the nanomaterials in industrial products. In addition, nanomaterials containing metals make further research necessary to design new materials for multifunctional applications in the future.

This Special Issue focuses on progress in synthetic technology of organometallic nanomaterials and their applications in biology, environmental science, drug delivery, sensing, and catalysis.
