Imaging beyond the difraction limit

Small Times summarizes this recent Applied Physics Letter: "Peering into the nano world with a nanolens".
"This is the best superlens realized so far, and is a significant development in the field of high-resolution optical imaging," said Srinivas Sridhar, prof. and chair of physics at Northeastern, in a statement.

Sridhar claims the group already has capabilities for large-scale production of the nanolenses, and wants to begin manufacturing "in the near future," he added. End applications include biomedical imaging and lithography techniques. The work is funded by the National Science Foundation and the US Air Force.
