New type of nanosensor detects DNA building blocks

Researchers at Uppsala University and in Brazil have developed a new type of nanosensor that can detect single molecules. The nanosensor, comprising a combination of two different materials, has been used to identify the ...

Invisible particles 'seen' for the first time

A new optical effect in nanoscale disks of silicon, namely patterns of radiation that do not emit or scatter light, has been observed by A*STAR researchers and international collaborators. These modes, which have never before ...

How spin dances with dipole

The key physical property of multiferroic materials is the existence of a coupling between magnetism and polarization. The origin and manifestations of magnetoelectricity can be very different in the available multiferroic ...
