Recent nanotechnology conversations point to understanding what happens to nano materials when used in the human body.
Now, scientists at Northwestern University have "devised a noninvasive method of imaging these nanostructured materials within the body, providing a way of tracking the fate of these materials in a living organism. These researchers have been developing a toolbox of synthetic amino acids (related to building blocks of proteins) that assemble themselves into complex structures that may prove useful in drug delivery and tissue engineering applications.

In addition, watchdog Pew Charitable Trusts recently launched "Project on Emerging Nanotechnologies at the Woodrow Wilson International Center for Scholars to ensure that the federal government and the private sector address the potential human health and environmental risks as well as the benefits of emerging nanotechnologies. The project works with industry, the government, and the scientific and public interest communities to identify gaps in nanotechnology risk-assessment research and oversight and to develop strategies to address them."
