Abstract: The invention relates to an Apparatus for the growth of artificial organic items, particularly human or animal skin. The growth of skin is possible if a slowly stretched piece of skin or skin substitute is in contact with the nutrient fluid only on its inner side, and in contact with a gas, especially with air, on its outer side.

Abstract: The invention relates to a Microchip for the detection of poor sources of electrical and/or magnetic fields. To detect such poor electrical sources hidden in a body is a difficult problem for which was found a solution by this invention. The invention solves this problem by a Microchip consisting of a plate with parallel rows of recesses, in each recess is a cristall with a magnetic activity, between the rows are one or more wires connected with a voltage source and one or more wires connected with a voltmeter, the whole surface of the plate with the cristals in the recesses and the wires is embeded in a layer of semiconducting polimeres.

Abstract: A Laminar Flow reactor for large scale culturing or packaging of cell suspensions, three-dimensional tissue and other biological systems is disclosed. The Laminar Flow reactor consists of an upper housing and a lower housing. The housings are interconnected by a plurality of connectors and a plurality of rigid spacers, an inlet fluid, an outlet fluid, a fluid reservoir, and a means for transporting fluid within the system. During treatment, liquid media is transported from the fluid reservoir to the inlet manifold, which will in turn evenly distribute the media to each of the connected connectors and internal culture pockets. Laminar flow through the device is maintained by the cylindrical shape of the device and by bypasses. An outlet fluid manifold is also provided to ensure that each treatment chamber is evenly filled and to ensure that any air bubbles formed during treatment are removed from the treatment chambers.

Abstract: The inventions relate to a method for producing a microchip that is able to detect infrared light with a semiconductor, the basic infrared light is absorber by the semiconductor surrounded, attached or embedded in a polymer which is brought in a thin layer on the surface of the semiconductor and which is grown by polymer around the semiconductor in an acid fluid.
