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 present invention describes a laminar flow bioreactor with improved laminar flow lines of fluids. The bioreactor housing defines a chamber adapted to receive a scaffold. An inlet aperture at one end of the chamber is in fluid communication with an outlet aperture at the opposite end of the chamber. A bypass mechanism selectively operable from an open position to a closed position consisting of an iris assembly directs a portion of fluid flowing through the chamber around the scaffold-receiving area. This bioreactor is inserted in a bioreactor system.

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.
