Abstract: A catheter with many fiber optic pressure sensors. The sensor diaphragm is formed from a wafer with a thin silicon layer and a silicon substrate layer separated by a silicon dioxide layer. A method includes masking and etching channels through the silicon substrate layer in a pattern of concentric circles to form a concentric circular etched channels and cylindrical unetched portions of the silicon substrate layer between the channels, exposing the silicon dioxide in the etched regions, and dissolving the exposed silicon dioxide to expose the crystalline silicon layer in the etched regions. The unetched cylindrical portion of the silicon substrate forms the diaphragm support element and the thin silicon layer forms the diaphragm. After applying a reflective coating to the exposed thin silicon layer, the support element face is adhered to the end face of a tubular housing, and a fiber optic probe is inserted in the tubular housing.

Abstract: A sensor for a selected analyte in a test sample has (a) a semipermeable membrane with pores for retaining the analyte, where the membrane has been chemically modified by attachment of membrane modifiers; (b) immunoassay labels which have label binding ligands where these label binding ligands will have a binding affinity for the membrane modifiers in the presence of the analyte, and a measurably different binding affinity for the membrane modifiers in the absence of the analyte; and (c) a label detecting system, for detecting the presence of the labels on the membrane.

The images may be read immediately, using scintillation, or may be stored in the glasses for subsequent reading using optically stimulated detrapping of stored charges.

Abstract: Self-organized polymolecular structures, including structures having a helical, tubular or needle-like morphology, are formed by the association of molecules of an amphiphilic 2,3 di-O-substituted tartaric acid compound and molecules of a bipyridyl compound. If the tartaric compound includes a polymerizable functional group, the polymolecular structures may be stabilized by polymerization.

Abstract: A thin-film edge field emitter device includes a substrate having a first portion and having a protuberance extending from the first portion, the protuberance defining at least one side-wall, the side-wall constituting a second portion. An emitter layer is disposed on the substrate including the second portion, the emitter layer being selected from the group consisting of semiconductors and conductors and is a thin-film including a portion extending beyond the second portion and defining an exposed emitter edge. A pair of supportive layers is disposed on opposite sides of the emitter layer, the pair of supportive layers each being selected from the group consisting of semiconductors and conductors and each having a higher work function than the emitter layer.

Abstract: Target moiety is detected by (a) providing an antibody specific to the target, (b) saturating the binding sites of the antibody with a labelled form of the target, (c) flowing a liquid containing the target past the saturated antibody, thereby (d) allowing the target to displace the labelled antigen, and (e) detecting the displaced labelled antigen with a detector for the label.

Abstract: A multimode waveguide device for assays includes a multimode waveguide with a patterned, reflective surface coating. The exposed portion or portions of the reflectively coated waveguide surface are for analyte recognition. A fluidics cell is attached to the waveguide so that the channel or channels of the fluidics cell match with the exposed portion or portions of the waveguide surface. The channel or channels direct one or more sample fluids over the exposed portion or portions of the waveguide surface. The reflective coating minimizes loss and scattering of excitation and fluorescence light during a fluorescence assay.

Abstract: A piezoelectric ceramic-polymer composite is made of a substantially two-dimensional polymer matrix and a monolayer of sintered piezoelectric ceramic granules dispersed throughout the matrix so that each granule has an upper portion protruding from one side of the matrix and a lower portion protruding from the opposite side of the matrix. The composite is formed by partially embedding a monolayer of sintered piezoelectric ceramic granules in a pliable material, then partially covering the granules with a polymer resin, curing the resin to form a matrix and removing the pliable material. A transducer is formed by flattening the upper and lower portions of the granules to form coplanar top and bottom surfaces parallel to, but not coplanar with the surface of the matrix, then electroding the granule surfaces, attaching top and bottom cover plates, and sealing the transducer around the edges.

Abstract: Wild-type bacteria with polyurethanase activity, and the ability to excrete polyurethanase into a culture medium have been genetically altered to significantly increase their polyurethanase activity. Biologically pure cultures of these genetically altered are cultured in a medium containing an inducer for the production of polyurethanase. The bacteria are then removed from the culture medium to provide a preparation with a high polyurethanase activity. One useful genetically altered bacteria is a strain of Pseudomonas chlororaphis designated ATTC No. 55729. The polyurethanase-containing preparation may then be used directly to degrade polyurethane, particularly polyurethane and polyurethane-based coatings.
