Nanotechnology presents new opportunities to create better materials and products. Nanomaterials find wide applications such as catalysis, fuel cell, and medicinal and technological applications, and nanomaterials containing products are already available in world markets including automotive, defense, drug delivery, coatings, computers, clothing, cosmetics, sports equipment, and medical devices. There is a need for research to better understand and apply information regarding nanomaterials such as controlled synthesis, sustainable and environmental friendly, characterization, and their applications. However, there are unanswered questions about the impacts of nanomaterials and nanoproducts on human health and environment. The special issue will become an international forum for researchers to summarize the most recent developments and ideas in the field, with a special emphasis given to the technical and observational results obtained within the last five years. Potential topics include, but are not limited to:

• Synthesis of nanomaterials
• Fabrication of nanomaterials
• Characterization
• Application of nanomaterials
• Nanocomposites
• Environmental remediation
• Toxicological studies of nanomaterials
