One of the companys first products are security markers that incorporate organic nanofibers, called nanomarkers. The work of Rubahn, professor at the University of Bonn, both in Germany, advances bottomup nanotechnology since it shows that it is possible to generate on large scale welloriented and welldefined nanostructures, the properties of which can be modified at will. Such control, in turn, is relevant for future organic electronics and photonics from flat screens to photonic circuits.

By Michael Berger, Copyright Nanowerk LLC Nanowerk Spotlight The vision of revolutionary bottomup nanotechnology is based on concept of molecular assembly technologies where nanoscale materials and structures selfassemble to microscale structures and finally to macroscopic devices and products. Until machinery capable of automated and industrialscale nanoassembly can be built, the parallelism of chemical synthesis and selfassembly is necessary when controlling materials at the nanoscale. Our nanofibers can be transferred easily and destructionfree as individual entities or in massive parallel fashion onto prestructured target substrates.

We are long way from realizing this vision but researchers are busily laying the foundation for nanoscale engineering. Rubahn has set up company Nanofiber AS to commercialize his research on organic nanofibers. The research team also points out that their novel concept is related to the morphology of the organic material as well as investigating the potential toxicity of the nanofibers. Rubahn, University of Southern Denmark The list of potential applications includes nanoscale frequency doublers, nanolasers with low threshold, generic nanosensor platforms etc.

Applications as passive and active elements in printed alloptical chips are within reach.. For there are still some basic challenges to be overcome, such as the stability of the organic material as well as investigating the potential toxicity of the nanofibers range from less than hundred to few hundred nanometers and millimeter. New research results coming out of Denmark offer the basis for novel organicmoleculebased nanotechnological concept that allows for multitude of applications in fundamental research and in device applications.

Due to their crystalline perfection and due to the morphological control, organic nanofibers are perfectly suited for fundamental studies of optics, mechanics, and electronics on the mesoscale.
