Abstract: The invention relates to a circuit or microchip for the detection of poor sources of (or very weak) electrical and/or magnetic fields. In one embodiment a device of the present invention includes a microchip consisting of a plate with a plurality of cells, each cell includes a crystal suspended in a semiconducting polymer and piece of metal wire. The cell is insulated by another polymer. A voltage is applied to parallel wires running on each side of the cell, thus inducing a first (or static, or initial) voltage when measured from the cell to the wire. Changes in magnetic or electrical fields are detected by noting a change in voltage from the cell, which is caused by the crystal changing orientation due to the change in the field the circuit is subjected to.

Abstract: The present invention includes a method for biomimetic-inspired infrared sensors utilizing a bottom up approach. This method includes providing a sinusoidal alternating electrical field between a preformed electrode gap comprising two gold micro-electrodes. Providing single needles of zinc phosphide crystals optimized for growth conditions using a physical vapour transport. Immobilizing at least one individual zinc phosphide nanowire in the preformed electrode gap using dielectrophoretic manipulation. And, placing and contacting the at least one individual zinc phosphide nanowire in the preformed electrode gap. Two nanowires are combined to form a lambda shape for improved sensing.

Abstract: The invention provides a process for producing a three-dimensional tissue by cultivating eucaryotic cells by introducing the cells into a matrix and cultivating the cells within the matrix in a cell culture medium within a cell culture vessel under controlled dissolved oxygen conditions of the cell culture medium. The matrix contains a support containing an optical oxygen sensor, which is an oxygen-sensitive dye, which upon irradiation with an excitation wavelength changes its emission characteristics in dependence on the dissolved oxygen concentration in the surrounding medium, including a dye phosphorescing upon irradiation of an excitation wavelength, which phosphorescence is quenched by dissolved oxygen.

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.
