Abstract: A microdialysis probe including a probe body, a supply line and a discharge line for a perfusion solution and a dialysis membrane, wherein a probe needle for introduction into a tissue is provided by a generally elongate frame. The frame has at least one recess at least partially open for receiving at least a portion of the supply and discharge lines. The invention encompasses a method for making such a probe, wherein the method includes arranging a dialysis membrane on a shaping device, shaping the dialysis membrane in a selected shape, applying an adhesive agent to the dialysis membrane to keep the membrane in the selected shape, and separating the dialysis membrane and the shaping devices after the adhesive agent has been applied.

Abstract: A microdialysis probe with a probe body, a probe needle for introduction into a tissue, an inlet line and an outlet line for a perfusion solution and a dialysis membrane, wherein at least one hollow channel forms the outlet line and extends at least partly spirally about the probe needle on an external surface of the probe needle. The inlet for the perfusion solution may also be in the form of spiral about the external surface of the probe needle.

Abstract: A needle for medical uses, for example for inserting a dialysis membrane into human or animal tissue, wherein the needle has an end portion made of solid material and provided with at least two areas which intersect a longitudinal axis of the needle and each other whereby at least one line or point of intersection is formed between the at least two areas, the line or point of intersection in a needle region adjacent to the end portion.

Abstract: A spectrometer is described with a new intensity detector for electromagnetic radiation. The detector comprises means for detecting the deflection of a cantilever which has a bimetallic/bimorph structure. The deflection is proportional to the absorbed amount of radiation.

Abstract: A recording and reproducing method for binary coded information and a suitable recording medium are described, which use endohedrally doped cagelike molecules 30, especially fullerenes and derivatives thereof, as storage elements. By applying a probing tip 36 to the molecule for the read/write process an enhanced storage density is achieved.

Abstract: An Auger electron microscope is equipped with a field-emission tip maintained at an essentially constant distance above the surface of the specimen. The tip may consist of a tungsten (100) whisker having a radius of .about.50 nm at the apex, the working distance being on the order of 1 mm. Auger electrons emitted from the surface of the specimen are collected by an electron energy analyzer for conventional processing. Mutual scanning displacement between the tip and specimen is obtained through use of an xyz-drive module, which is also responsible for adjusting the working distance of the tip. The entire microscope setup is mounted on vibration damping means and may be inserted into a vacuum system by means of an appropriate flange, if desired.
