Challenges of Nanotechnology
[attachment=23373]
grand challenges for nanotechnology
The five main challenges are to develop instruments to assess exposure to engineered nano-materials in the air and water and we think that that challenge will take three to ten years. The emergence of new nano-technologies we feel that there is a very real need to monitor exposure to humans in the air and within water. The challenge becomes increasingly difficult in more complex matrices like food.
The second challenge would be to develop and validate methods to evaluate the toxicity of engineered nano-materials within the next 5 to 15 years.
How should nanotechnology programs be governed and controlled?
The Food and Drug Administration attempts to ensure materials that are safe and effective. EPA ensures that there is no demonstrable harm to an environment or to people in that environment. Nano-materials are just another instance of the wide array of technologies that we have developed. The regulatory agencies need to have adequate resources to monitor nano molecules properly.
To address these 5 challenges
Pool resources internationally and with the issue of hazard identification of, exposure to, and risk analysis of engineered nano-materials.
Many assumptions about risk assessment and risk management that work in the macro world we all inhabit will also work for nanotechnology and nanomaterials, but some issues may be unique to nanomaterials because of their small size.
Genome annotation
In the context of genomics, annotation is the process of marking the genes and other biological features in a DNA sequence. The first genome annotation software system was designed in 1995 by Dr. Owen White, who was part of the team that sequenced and analyzed the first genome of a free-living organism to be decoded, the bacterium Haemophilus influenzae.
