Professor Elizabeth M. Nolan has been awarded an NIH Innovator Award. The award supports exceptionally creative new investigators who propose highly innovative projects that have the potential for unusually high impact. Professor Nolan's new research program will focus on elucidating synergies between naturally-occurring antimicrobial peptides and metal ion homeostasis.

Justin Kim of the Movassaghi group has developed a highly stereoselective and systematic strategy for the introduction of polysulfides in the synthesis of epipolythiodiketopiperazines. Application of this strategy has yielded the total synthesis of the di-, tri-, and tetrasulfides (+)-chaetocin A, (+)-chaetocin C, and (+)-12,12'-dideoxychetracin A, respectively. The synthesis of the latter two represents the first total synthesis of dimeric epitri- and epitetrathiodiketopiperazines. more>> |

In collaboration with the Bulovic group in Electrical Engineering and Computer Science, Moungi Bawendi and Brian Walker have developed a new method to deposit J-aggregates and colloidal quantum dots together in a solid state thin film.

The resulting blended materials exhibit near-unity energy transfer efficiencies and result in an increase in the absoprtion cross sectionat the J-aggregate resonance--making these films interesting for applications in photoluminescence downconversion and basic studies of light harvesting. |

By creating a better way to see molecules at work in living brain cells, researchers affiliated with MIT’s Picower Institute for Learning and Memory and the MIT Department of Chemistry (Ting Lab) are helping elucidate molecular mechanisms of synapse formation. These studies could also help further understanding of how synapses go awry in developmental diseases such as autism and Fragile X syndrome. The study appears in the Oct. 7 issue of Cell. More>> |

Addressable Terminally Linked DNA−CNT Nanowires
Yossi Weizmann, David M. Chenoweth, and
Timothy M. Swager
J. Am. Chem. Soc. 2010, 132, 14009–14011
The Swager group has reported the novel assembly of carbon nanotube (CNT) DNA oligomers by the regiospecific functionalization of the CNTs. They show that the oligonucleotides junctions are addressable and can be targeted by gold nanoparticles. These materials can be used to span gaps between electrodes and are being used to create novel sensory devices. |
