Committee debates future of nanotechnology

Nanotechnology stands to revolutionise many fields of science, and is already making great leaps forward in chemical engineering, biotechnology, medical, and even cosmetic and leisure applications. However, without appropriate legislation, any environmental and health risks cannot be appropriately anticipated and dealt with.

A US Senate enquiry has heard from key names in the field of nanotechnology to examine current and future applications for nanotechnology, obstacles facing its development and safety and legislative aspects concerning its use.

Committee Co-Chairman US Senator Daniel K. Inouye delivered one of the opening speeches with a warning that the progress of nanotechnology resembles that of asbestos before any of its deleterious effects were known. Nanotechnology is fast on the way to becoming ubiquitous but only a small proportion of research money is being put towards environmental, health and safety issues, and even less to long-term studies.

Dr. Clayton Teague, Director of the National Nanotechnology Coordinating Office reported that the US Federal government invests over $1 billion a year in nanotechnology. He highlighted photovoltaic cells as a major direction with obvious environmental and economic benefits. He emphasised the need for international cooperation to bring new applications to the fore. Tools for measuring and monitoring exposure to nanoparticles are in development and will be necessary for ongoing health and safety.
