New Bioimaging Technique Is Fast and Economical

IntesNature.jpg

A new approach to optical imaging makes it possible to quickly and economically monitor multiple molecular interactions in a large area of living tissue – such as an organ or a small animal; technology that could have applications in medical diagnosis, guided surgery, or pre-clinical drug testing.

Researchers Create Molecular Movie of Virus Preparing to Infect Healthy Cells

A research team has created for the first time a movie with nanoscale resolution of the three-dimensional changes a virus undergoes as it prepares to infect a healthy cell. The scientists analyzed thousands of individual snapshots from intense X-ray flashes, capturing the process in an experiment at the Department of Energy’s SLAC National Accelerator Laboratory.

Researchers Working on Blood Test to Detect Brain Metastases While Still Treatable

Houston Methodist cancer researchers are now closer to creating a blood test that can identify breast cancer patients who are at increased risk for developing brain metastasis, and also monitor disease progression and response to therapy in real time.

Multicolor MRIs Could Aid Disease Detection

Researchers at Case Western Reserve University School of Medicine have developed a method that could make magnetic resonance imaging—MRI—multicolor. Current MRI techniques rely on a single contrast agent injected into a patient’s veins to vivify images. The new method uses two at once, which could allow doctors to map multiple characteristics of a patient’s internal organs in a single MRI. The strategy could serve as a research tool and even aid disease diagnosis.

Drug-Delivering Micromotors Treat Their First Bacterial Infection in the Stomach

Nanoengineers at the University of California San Diego have demonstrated for the first time using micromotors to treat a bacterial infection in the stomach. These tiny vehicles, each about half the width of a human hair, swim rapidly throughout the stomach while neutralizing gastric acid and then release their cargo of antibiotics at the desired pH.

Single Molecules Can Work as Reproducible Transistors—at Room Temperature

Venkataraman-Lovat_Nature-NanotechWEB.jpg

Columbia researchers published a study today in Nature Nanotechnology that is the first to reproducibly demonstrate current blockade—the ability to switch a device from the insulating to the conducting state where charge is added and removed one electron at a time—using atomically precise molecular clusters at room temperature. The study shows that single molecules can function as reproducible circuit elements such as transistors or diodes that can easily operate at room temperature.
