Abstract: Bacterial spores can be rapidly and sensitively detected and quantified based upon molecular recognition of unique chemicals in the spore coat. Spores can be detected and assayed based upon the calcium concentration in bacterial spore coats using the calcium which is unique to the bacterial spores. Since spores contain a high concentration of calcium relative to other biological materials, fluorescent calcium-sensitive indicators are used to detect Ca+2 displaced from the spore case or free in solution or from the aerosol phase. Visibly excitable fluorescent dyes provide a sensitive and selective means to monitor changes in spore concentration and avoid difficulties associated with laser or UV-excitation.

Abstract: An implantable substrate sensor has electronic circuitry and electrodes formed on opposite sides of a substrate. A protective coating covers the substrate, effectively hermetically sealing the electronic circuitry under the coating. Exposed areas of the electrodes are selectively left uncovered by the protective coating, thereby allowing such electrodes to be exposed to body tissue and fluids when the sensor is implanted in living tissue. The substrate on which the electronic circuitry and electrodes are formed is the same substrate or “chip” on which an integrated circuit (IC) is formed, which integrated circuit contains the desired electronic circuitry. Such approach eliminates the need for an hermetically sealed lid or cover to cover hybrid electronic circuitry, and allows the sensor to be made much thinner than would otherwise be possible. In one embodiment, two such substrate sensors may be placed back-to-back, with the electrodes facing outward.

The etching process is stopped upon occurrence of a predetermined spectral event sensed by the emission intensity level detector.

An inner layer made of, e.g., AlGaN is formed in the top crystal layer. Development of dislocations is suppressed to some extent by the lateral growth when forming the intermediate crystal layer and the top crystal layer. Further, development of dislocations is suppressed by the inner layers.

Abstract: A structure and method for providing an antifuse which is closed by laser energy with an electrostatic assist. Two or more metal segments are formed over a semiconductor structure with an air gap or a porous dielectric between the metal segments. Pulsed laser energy is applied to one or more of the metal segments while a voltage potential is applied between the metal segments to create an electrostatic field. The pulsed laser energy softens the metal segment, and the electrostatic field causes the metal segments to move into contact with each other. The electrostatic field reduces the amount of laser energy which must be applied to the semiconductor structure to close the antifuse.
