Excerpt

This month’s issue opens with an amazing new development: microscopy without a microscope! That is, without a microscope as we know it. Zhang et al. (DOI 10.​1007/​s00428-015-1782-z) reasoned that the conventional light microscope suffers from bulky size, lack of portability, and relatively high cost, which limit its use notably in low resource situations. As a solution, they developed a lens-free on-chip imaging platform. The image quality is quite comparable with that of a conventional microscope or a virtual slide prepared using a bulky scanner. Diagnostic performance (albeit on a limited set of samples) is equal to that of conventional microscopy. The lens-free computational microscopy platform holds high promise for applications in pathology, especially where resources are limited. …
