The Fraunhofer IPMS presents an alternative with its “Scanning Photon Microscope”. It works on a similar principle but uses a two-dimensional resonant microscanning mirror developed at the Fraunhofer IPMS for the deflection of light. Various possibilities for miniaturization of the system result from the minimal dimension of the mirror (4 x 3 mm2).
The presented demonstrator with a dimension of 4 x 10 x 20 cm collects pictures of 1000 x 1000 pixels with a resolution of 10 µm per pixel. Therefore the image area is 1 x 1 cm. By changing the optical design it is possible to increase the performance parameters. Very interesting for future applications is the possibility to choose the wave length of the radiated light and therefore to activate processes like fluorescence and to evaluate them wave length specific.
Non-destructive testing, e.g. to detect microcracks, or the biotechnology are potential fields of application. Measurements are possible both in the illuminated area and in the dark field.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
