Danes set world record in catching nano gold A new world record has been set by biophysicians from the Niels Bohr Institute at Copenhagen. Their mission was to catch particles of gold with three dimensional light.

A strongly focused laser beam was used to catch the gold particles, a pair of so called optical tweezers. The biophysicians managed to pick up gold particles with a diameter of 250 nano meters thus setting a new world record. The result was a considerable improvement of the previous record of 40 nano meters in diameter.
As of now the scientists are experimenting with injecting the gold particles into living organisms. The particles will be used as tiny nano machines that can measure power and distance. Hopefully the technology can be used in future nano surgery.
The world record results will be presented in the prestigious publication Nano Letters later this week.
The Niels Bohr Institute the part of Copenhagen University working with physics, geophysics, biophysics, nanotechnology and astronomy.
