Optical microscopes and tweezers can image and manipulate objects at the microscale for applications in cellular and molecular biology. The optical resolution is, however, hampered by the diffraction limit and therefore both ...
Scientists from Tomsk Polytechnic University together with colleagues proposed using special diffraction gratings with gold plates instead of microlenses used in the classic configuration to obtain images in nanoscopes. Microlenses ...
