Sharp Corners and Kaleidoscopes Lead to Novel Microscopy Techniques
Researchers at Harvard Medical School in Boston have developed two microscopy techniques: a near-field method that offers potentially better performance than other superresolution techniques and a “mirror tunnel” approach that promises high-resolution, wide-field imaging.
The first, dubbed differential near-field scanning optical microscopy, overcomes one of the problems with conventional aperture-based subwavelength imaging. The resolution of such methods is set by the aperture size, with...
