Insoluble or low-solubility nanoparticles in biological fluid are the greatest cause for concern. Because of their tiny size, several studies have shown behaviour unique to NP. Some of them can pass through our various defence mechanisms and be transported through the body in insoluble form. Thus, some NP can end up in the bloodstream after passing through all the respiratory or gastrointestinal membranes. They are then distributed to various organs and accumulate at specific sites. Others travel along the olfactory nerves and penetrate directly into the brain, while still others pass through cell barriers and reach the nucleus. | The National Nanotechnology Initiative Environmental Health and Safety Research Needs for Engineered Nanoscale Materials About the National Science and Technology Council The National Science and Technology Council NSTC was established by Executive Order on November 23 1993. The Cabinet-level council is the principal means by which the President coordinates science space and technology policies across the Federal Government. NSTC coordinates the diverse parts of the Federal research and development enterprise. An important objective of the NSTC is the establishment of clear national goals for Federal science and technology investments in areas ranging from nanotechnology and health research to improving transportation systems and strengthening fundamental research. The Council prepares research and development strategies that are coordinated across Federal agencies to form a comprehensive investment package aimed at accomplishing multiple national goals. NSTC s Nanoscale Science Engineering and Technology NSET Subcommittee is the interagency body responsible for coordinating planning implementing and reviewing the National Nanotechnology Initiative NNI . The National Nanotechnology Coordination Office NNCO provides technical and administrative support to the NSET Subcommittee and supports the subcommittee in the preparation of multi-agency planning budget and assessment documents including this report. Please call the NSTC Executive Secretariat at 202-4566101 to obtain additional information regarding the NSTC or visit the NSTC website at nstc . More information on the NNI the NSET Subcommittee and NNCO is available at 703-292-8626 or on the NNI website at . About the Office of Science and Technology Policy The Office of Science and Technology Policy OSTP was established by the National Science and Technology Policy Organization and Priorities Act of 1976. OSTP s responsibilities include advising the President in policy formulation and .
