Nanorods Propelled Ultrasonically Spin at a Dizzying Rate

Nanorods Propelled Ultrasonically Spin at a Dizzying Rate

Vibrate a solution of rod-shaped metal nanoparticles in water with ultrasound and they'll spin around their long axes like tiny drill bits. Why? No one yet knows exactly. But researchers at the National Institute of Standards and Technology (NIST) have clocked their speed—and it's fast. At up to 150,000 revolutions per minute, these nanomotors rotate 10 times faster than any nanoscale object submerged in liquid ever reported. [More]

Researchers Employ Magnetized Carbon Nanotubes to Extract Biomolecules from Live Cells

University of Houston researchers have devised a new method for extracting molecules from live cells without disrupting cell development, work that could provide new avenues for the diagnosis of cancer and other diseases. [More]
Novel Protein Biomarker Test Platform May Improve Diagnostic Testing

Novel Protein Biomarker Test Platform May Improve Diagnostic Testing

A new protein biomarker test platform developed by researchers at the University of Michigan and Indiana University promises to improve diagnostic testing. The test can accurately and simultaneously measure multiple proteins that indicate the presence of diseases like graft-versus-host disease (bone marrow transplant rejection) in only two hours, no washing steps, and using only a minute volume of blood plasma. A report on this new technology can be found online in the journal TECHNOLOGY. [More]

New Self-Assembling Nanoparticle Enables Early Diagnosis of Cancer

Scientists have designed a new self-assembling nanoparticle that targets tumours, to help doctors diagnose cancer earlier. [More]
DNA Nanopyramids Can Flag and Kill Bacteria

DNA Nanopyramids Can Flag and Kill Bacteria

Bacterial infections usually announce themselves with pain and fever but often can be defeated with antibiotics — and then there are those that are sneaky and hard to beat. Now, scientists have built a new weapon against such pathogens in the form of tiny DNA pyramids. [More]
Researchers Employ DNA Origami to Test Theories About Cell Signalling

Researchers Employ DNA Origami to Test Theories About Cell Signalling

Researchers at Karolinska Institutet in Sweden have headed a study that has provided new knowledge about the EphA2 receptor, which is significant in several forms of cancer. This is important knowledge in itself – but just as important is how this study, which is published in the highly respected journal Nature Methods today, was conducted. [More]
SOS Molecules Corralled Into Nanofabricated Patches Trap Membrane-Associated Ras Molecules

SOS Molecules Corralled Into Nanofabricated Patches Trap Membrane-Associated Ras Molecules

A breakthrough discovery into how living cells process and respond to chemical information could help advance the development of treatments for a large number of cancers and other cellular disorders that have been resistant to therapy. [More]
Cooperation in Heat Shock Protein Observed Using Foerster Resonance Energy Transfer Methodology

Cooperation in Heat Shock Protein Observed Using Foerster Resonance Energy Transfer Methodology

As in a successful football match, all actors in a cell must play in perfect coordination. A typical example for this kind of cooperation can be seen in the heat shock protein Hsp90, which controls the proper folding of other proteins. Together with a second molecule, the co-chaperone P23, it splits the energy source ATP to release the energy it needs to do its work. [More]
