Nanomaterials – Whither goest thou

History and Future

Nanoparticles in the form of soot and particulate matter have always been byproducts of combustion (log-fires, cigarette smoke, diesel engines, candles,...) but have not resulted from inventions of modern science.

Although these byproducts are usually undesirable, nanoparticles have also been selectively employed for a very long time. Soot was used in cave paintings as early as the Stone Age. Throughout the ancient world and the middle ages, lead sulfide particles, carbon nanotubes, iron carbide wires and nano gold particles were used to dye hair, to forge steel and to manufacture cranberry glass.

The use of nanoparticles was certainly not a conscious choice by those manufacturing nor those benefiting from the end products. The knowledge of the existence of nanoparticles is new, as well as the selective research into nanoparticles for specific applications as well as their controlled production and use.

• Nanomaterials serve to produce lighter and more durable products, they add features to products and assist in considerably increasing the yield of energy generation.

In this manner, natural resources are conserved and the sustainability of products is facilitated. A more efficient management of our resources saves money and preserves the environment.

Nanomaterials will undoubtedly become the central issue of innovation in business for the next decades and enviromental agencies are assigned with the task and the responsibilty of being actively involved in the shaping of their development and their advance.
