More than a decade ago, theorists predicted the possibility of a nanolens -- a chain of three nanoscale spheres that would focus incoming light into a spot much smaller than possible with conventional microscopy. Such a device would make possible extremely high-resolution imaging or biological sensing. But scientists had been unable to build and arrange many nanolenses over a large area. Now, new advances in nanolensing would make possible extremely high-resolution imaging or biological lensing.
