Fabrication of planar organic nanotransistors using low temperature thermal nanoimprint lithography for chemical sensor applications.

A new fabrication process for the patterning of organic semiconductors at the nanoscale has been developed using low temperature thermal nanoimprint lithography and the details of this process are discussed. Novel planar nanotransistors have been fabricated and characterized from poly(3-hexylthiophene) (P3HT) and we demonstrate the feasibility of using such devices as highly sensitive chemical sensors.

Preliminary experimental experiences with xenotransplantations.

In our xenotransplantation experiments has been a major aim to induce specific tolerance. The results from the meeting of the donor's and the recipient's immunocompetent systems already in the period of embryonic development and/or the influence of methylprednisolone are described.
