n the world of nanoscience, as surface areas increase relative to volume, materials can take on intriguing new properties. Insulators can become conductive, soft materials can display incredible


nanoscience are immense and nanotechnology touches almost all areas of human endeavour, from advanced technologies and silicon chips to medical devices and new ways to treat and diagnose disease. A nanoscale material is defined as, “A material with one or more dimensions of <100 nm.”1


In practice,


nano has come to describe many different forms of materials and technologies such as nanowires, nanosheets, nanocrystals, nanobiology, nanoscience and
