Chemists create 'Superbowl' molecule; May lead to better health

...les," says study leader Michael Sherburn, Ph.D., a chemist with Australian National University in Canberra. "These new molecules have much greater capacity and selectivity than their predecessors and show more promise for wider applications." "I wanted a name for our compounds which acknowledged this and re...

Nano-Probes Allow an Inside Look at Cell Nuclei

...bers of the lab of Paul Alivisatos, a Berkeley Lab chemist in the Materials Sciences Division and Associate Laboratory Director who helped pioneer the development of nano-sized crystals of semiconductor materials. Called quantum dots, these microscopic crystals have shown promise in such wide-ranging applica...

Newly Discovered Compound Blocks Known Cancer-Causing Protein

... had identified cysmethynil, they worked with Duke chemist Eric Toone and chemistry graduate student David Gooden to synthesize the molecule and verify its chemical structure. A search of the chemical literature turned up no previous description of the chemical, leading the scientists to believe they had dis...

Study uncovers bacteria's worst enemy

...the journal Environmental Microbiology, Laboratory chemist Mary Neu and her colleagues describe their study of different naturally occurring bacteria used to treat actinide contamination. Actinides are the elements above atomic number 89 and are usually radioactive. The study's results indicate that actinide...

Chemical Engineer Kao Explores Antibiotic Synthesis With DNA Chips

..., immunosuppressants and anti-cancer drugs that no chemist can synthesize. Bacteria normally produce antibiotics to inhibit other bacterial strains competing for resources. Pharmaceutical companies exploit this property to manufacture drugs, but the process of cultivating bacteria is slow and costly. By hija...

Breakthrough: Scientists create world's tiniest organic particles

...s organic compounds have been very successful, the chemist said. New studies with mice have recently begun at the UNC School of Medicine, which DeSimone joined as professor of pharmacology. "The process starts off when we make a master template in a clean room at places like the Triangle National Lithograph...

Quantum dots provide a faster, more sensitive method for detecting respiratory viral infections

...one of the first medical uses of nanotechnology, a chemist and a doctor who specializes in infectious childhood diseases have joined forces to create an early detection method for a respiratory virus that is the most common cause of hospitalization among children under five. Respiratory syncytial virus (RSV...

Nanotubes inspire new technique for healing broken bones

...erials such as bone," says Robert Haddon, Ph.D., a chemist at the University of California, Riverside, and lead author of the paper. Single-walled carbon nanotubes are a naturally occurring form of carbon, like graphite or diamond, where the atoms are arranged like a rolled-up tube of chicken wire. They are ...

A radical solution for environmental pollution

...ness the reactive chemistry of free radicals. To a chemist it's an elegant solution to a difficult problem---even if we still don't really understand how the enzymes that catalyze these reactions work, for everyone else it could mean less pollution." ...
