Abstract: A magnetic bead assisted sampling system for a fluid sensor. Magnetic beads are dispersed in a sampling volume for collecting the analyte. The beads are packed into a small volume for pre-concentration of the analyte. A solvent may be applied to the beads to elute the analyte from the beads for movement to an analyzer.

Abstract: Solar cells and methods for manufacturing solar cells are disclosed. An example solar cell includes a first electrode and a second electrode. A first active layer may be disposed between the first electrode and the second electrode, and a second active layer different from the first active layer may also be disposed between the first electrode and the second electrode. One or more layers of conductive material may be disposed between the first active layer and the second active layer, if desired. In some instances, the first active layer may be sensitive to a first range of wavelengths, and the second active layer may be sensitive to a second range of wavelengths, where at least part of the first range of wavelengths does not overlap at least part of the second range of wavelengths. It is contemplated that more than two active layers may be used, if desired.

Abstract: Flexible microconduits integral at a proximal end to a substrate and adapted for connection to a biological environment at the distal end are provided. Also provided are microsystems with at least one flexible microconduit integral at a proximal end to a substrate and with a distal end that is adapted for connection to a biological environment. The microconduits may be fluid conduits, electrical conduits, or electro-fluidic conduits that transmit both fluids and electrical signals. Methods for fabricating the microconduits and other structures integral with the substrate are also provided.

Abstract: A solid state X-ray detector (106) is disclosed which is comprised of a plurality of Spherical ICs (202)-(208) disposed on a substrate (210). The Spherical ICs each have a plurality of detector picture elements (pixels) (302) disposed on the surface thereof. Each of the pixels (302) is formed from a layer of hydrogenated amorphous silicon (502) with a heavy metal layer (504) of molybdenum (Mo) disposed thereon as the cathode and a metal layer (508) disposed on the lower surface thereof. The cathode is reverse biased and X-rays impinging thereon will cause a transfer of electron-holes to the lower plate, which are stored on a capacitor (608). The electrons are accumulated over a predetermined period of time and then sampled and processed for output on a display (12) in real time or for storage of a digital value in a memory (114).

Abstract: A system and method for performing plasma etch on a spherical shaped device is disclosed. The system includes a processing tube for providing a reactive chamber for the spherical shaped substrate and a plasma jet is located adjacent to the processing tube. The plasma jet includes a pair of electrodes, such as a central cathode and a surrounding anode, for producing a plasma flame directed towards the reactive chamber. The central cathode may, for example, be powered by a radio frequency power source. As a result, the reactive chamber supports non-contact etching of the spherical shaped substrate by the plasma flame.

Abstract: An apparatus and method for separating fluid from a device such as a spherical shaped semiconductor integrated circuit. To this end, one embodiment provides a first area for receiving the device, a reducing area registering with the first area, a first passage centered in the reducing area, and a second passage adjacent the first passage. The pressure inside the first area is greater than the pressure inside the reducing area. Also, the pressure inside the first passage is greater than the pressure inside the second passage. The device moves through the first area and into the reducing area. Once in the reducing area, the device is inclined to enter the first passage while at least part of the fluid is inclined to enter the second passage. As a result, the fluid is thereby separated from the device.
