Nanotechnology Regulation
New federal guidelines for nanotechnology were proposed by the Environmental Protection Agency and the Food and Drug Administration June 9th. EPA regulations address nanoscale materials primarily in pesticides and define "nanoscale" based on the size of the material; whereas FDA regulations consider both a material's size and other properties (composition, etc.) in regulation.

Tumor Targeting through Communicating Nanoparticles
Bioengineer Sangeeta Bhatia (MIT) in collaboration with Michael Sailor (University of California San Diego) have constructed particles that mimic the clotting mechanism in vivo to enhance tumor targeting. The tumor location was identified using either gold nanoparticles, which induced heat-related damage in the tumor vasculature, or a human targeted protein tissue factor that identifies receptors associated with angiogenesis to initiate the clotting protein cascade. Then, iron oxide nanoworms or doxorubicin-loaded liposomes were directed to tumor sites for imaging and treatment, respectively, via targeting ligands that participate in the fibrinogen to fibrin conversion pathway. This approach substantially increased drug localization to the tumor site.

"Scotch Tape" for Nanotube Sorting
Carbon nanotubes (CNT) offer great promise in the electronics industry but are usually manufactured in a mixture of metallic and semiconducting structures. Researchers at Peking University led by Jin Zhang have exploited differences in CNT electrical properties to create surfaces for selective adhesion. These surfaces, modeled loosely on the idea of sticky "scotch tape", can be modified to selectively sort either semiconducting or metallic tubes and are expected to increase the availability of homogenous CNT structures.

A Further Step Toward Nanowire Computers
The promise of nanowire computers has been hindered by the inability to construct uniform nanowire components and integrate them with other electrical elements. Charles Lieber (Harvard) and colleagues have overcome some of these challenges by constructing computational logic gates using Ge/Si core/shell nanowires. These nanowires could function as field effect transistors (FETs) and could be used to drive other circuit elements. These nanowire circuits could greatly enhance the commercialization of nanowire computing.

Cloaked Nanoparticle Target Hypoxic Tumors
MIT Chemical Engineer Paula Hammond and colleagues have developed new nanoparticles based on layer-by-layer assembly that can shed their outer layer to improve tumor targeting. The particles consist of a pH sensitive outer polymer layer that dissolves at the lower tumor pH to reveal a charged nanoparticle that is rapidly internalized. These particles can thus selectively target tumors increasing the efficacy of chemotherapeutic drugs.

Society Award Winners
The NSEF is proud to announce that the 2011 NSEF Forum Award will be awarded at the AIChE annual meeting to Professor Brian A. Korgel (University of Texas at Austin – Department of Chemical Engineering). Dr. Korgel is this year's recipient of the NSEF Forum Award "for pioneering contributions to the art of nanocrystal and nanowire synthesis, elucidation of fundamental aspects of self-assembly, and development of new technologies based on nanomaterials." Dr. Korgel wil be discussing his research at the AIChE National Meeting in Minneapolis on Monday, October 17th during the NSEF Plenary Session. Please visit the on-line program to read the presentation abstract and for more information regarding the session.
Additionally, the 2011 NSEF Young Investigator Award will be awarded to Professor Suljo Linic (University of Michigan - Department of Chemical Engineering). The Young Investigator Award recognizes outstanding interdisciplinary research in nanoscience and nanotechnology by engineers or scientists in the early stages of their professional careers (within 10 years of completion of highest degree). Dr. Linic is this year's recipient of the NSEF Young Investigator Award "for contributions in energy conversion through the development of energy efficient and environmentally friendly nanomaterials for catalysis and photocatalysis."Dr. Linic will also be presenting during the October 17th plenary session (abstract and additional information also found in the on-line program) |

Annual Meeting Update
This year’s AIChE Annual Meeting will take place October 16th through October 21st in Minneapolis, with core programming beginning Monday morning, October 17th. NSEF is sponsoring or co-sponsoring 50 independent sessions, kicking off with our annual plenary that includes presentations from the two NSEF award winners and three distinguished, invited speakers who will discuss ongoing and future nanotechnology research from the government perspective (the Environmental Protection Agency, the Department of Defense, and the Department of Energy). Please help kickoff the week of nano-programming by joining us at this session.
NSEF will also continue the tradition of holding an informal reception to encourage networking. This non-ticketed (free) event is open to all and is scheduled immediately following the close of sessions on Wednesday, October 19th through approximately 7:30. Everyone is welcome and encouraged to attend, whether long-time NSEF members or those simply wishing to learn more about the Forum. Plaques will be presented to the NSEF awardees and light horsdeuvors will be served.
Additional highlights pertaining to programming are presented below. |
