Imaging nanometer-scale objects with visible light is difficult for lens-based systems because the diffraction limit of the lens material restricts the instrument's resolution. Kwang S. Kim of South Korea's Pohang University of Science & Technology, Philip Kim of Columbia University, and coworkers report one way to beat the diffraction limit via nanoscale spherical lenses made by the self-assembly of calix[4]hydroquinone (Nature 2009, 460, 498). The researchers fabricated the lenses by slowly . . .
