Researchers build nanoscale autonomous walking machine from DNA

Researchers have developed a nanoscale machine made of DNA that can randomly walk in any direction across bumpy surfaces. Future applications of such a DNA walker might include a cancer detector that could roam the human body searching for cancerous cells and tagging them for medical imaging or drug targeting.

Preventing dental implant infections with silver nanoparticles

One million dental implants are inserted every year in Germany, and often they need to be replaced due to issues such as tissue infections caused by bacteria. In the future, these infections will be prevented thanks to a new plasma implant coating that kills pathogens using silver ions.

New imaging technology is advance for medical diagnostics, research

The new technique works by 'coding' individual photons from a pulsing laser with a megahertz radio frequency and then collecting those photons with a detector after they have interacted with tissue.

Magneto-optics on the edge

Scientists have reported on a massive increase of magneto-optical effects near the edges of nano-scale disks, where enhancements of over 1000% can be produced.

Incompressible Electrons

An international team of physicists discovered a condition by which electrons trapped on the surface of liquid helium become incompressible at very low temperatures and under microwave radiation.

Engineers design magnetic cell sensors with new protein nanoparticles

Engineers have designed magnetic protein nanoparticles that can be used to track cells or to monitor interactions within cells. The particles are an enhanced version of a naturally occurring, weakly magnetic protein called ferritin.

Scientists design a full-scale architecture for a quantum computer in silicon

Physicists have designed a scalable 3-D silicon chip architecture based on single atom quantum bits, providing a blueprint to build operational quantum computers.
