Scientists creating ‘golden bullet’ for cancer

Washington, Mar 13 (ANI): Researchers at Washington University in St. Louis are developing what they call a magic ‘golden’ bullet for cancer, which could kill the tumours by using gold nanoparticles.
The researchers— including Dr. Younan Xia, James M. McKelvey, Michael J. Welch— described the successful photothermal treatment of tumours in mice by using gold bullets, [...]

Scientists create multipurpose Swiss Army knife for nanomedicine

London, July 28 (ANI): By combining two nanoparticles in one tiny package, University of Washington researchers have created a Swiss Army knife of sorts for medical imaging and therapy.

The multipurpose nanotechnology tool could perform wide range of medical uses – imaging tumours, carrying drugs, delivering pulses of heat.

“This is the first time that a semiconductor [...]

Scientists come a nano-step closer to weighing a single atom

Melbourne, July 28 (ANI): In a new study, a team of scientists has understood how nanoparticles lose energy, thus coming a key step closer towards producing nanoscale detectors for weighing any single atom.

In this study, the team from the University of Melbourne, Argonne’s Center for Nanoscale Materials in Illinois and the University of Chicago synthesized [...]

Nanoparticles’ colour-changing ability makes it possible to create self-erasing documents

London, July 9 (ANI): Scientists have developed a film that exploits the colour-changing ability of nanoparticles, and can make it possible to create documents that wipe themselves clean after they’ve been read.

Northwestern University researchers in Evanston, Illinois, have revealed that they made the film by coating gold nanoparticles with a layer of hair-like molecules called [...]

‘Chemical nose’ can sniff out cancer

Washington. June 23 (ANI): Researchers at the University of Massachusetts Amherst have developed a ‘chemical nose’ that can sniff out cancer.

The revolutionary tool contains an array of nanoparticles and polymers that differentiate not only between healthy and cancerous cells but also between metastatic and non-metastatic cancer cells.

Currently, detecting cancer via cell surface biomarkers has taken [...]

Coffee stains to inspire cheaper TV screens of tomorrow

London, March 2 (ANI): In a new research, scientists have been inspired by coffee stains to suggest a cheaper option of making transparent conductive coatings for TV screens in the future.

In LCDs (liquid crystal displays), transparent conductive coatings are used to form an electrode on the surface of the screen, while in plasma TVs they [...]

Synthetic ‘good cholesterol’ designed to keep heart problems at bay

Washington, Jan 10 (ANI): Fearing that gorging on chocolate cake and juicy beef roast might send your blood cholesterol levels sky high? Well then here’s your ultimate saviour- synthetic high-density lipoprotein (HDL).

Scientists at Northwestern University have designed synthetic HDL, the “good” cholesterol, which could help fight chronically high cholesterol levels and the resulting deadly heart [...]
