Abstract: An approach is described that combines distinct properties of a specialized porous nitrocellulose film (PNC) with quantum nanoparticles to create an improved assay and detection sensitivity, permitting the development of a camera-based imaging system for fluorescent detection of macromolecules in microarray format. The two properties of PNC that facilitate the approach are an extraordinarily high binding capacity and a newly observed internal scattering of light. Quantum nanoparticles complement these PNC properties by providing a higher level of emitted light than the fluorescent dyes in common microarray use. Overall, the approach allows for instrument cost savings, reduced imaging time, and the ability to remotely image.

Abstract: Horizontally layered tablets, methods of making the horizontally layered tablets, and tableting equipment capable of producing the horizontally layered tablets are described. The horizontally layered tablets can be produced by simultaneously feeding a segregated flow of different compositions that form the respective layers of the tablet.

Abstract: A system for dispensing water treatment compositions into a pool, spa, or other body of water is disclosed, which system provides a visible cue that the water treatment is properly dispersing and also provides a visible cue when the desired amount of water treatment has been dispensed. The system comprises a dispenser and the water treatment composition contained within the body of the dispenser, which dispenser and which system provides a readily visual cue that when the water treatment dose has been fully, or in some cases mostly or partially dispersed. For example, the dispenser sinks when fully dosed and resurfaces when empty, and in particular embodiments the water treatment generates visible gas bubbles and/or a color stream as the treatment dissolves.

Abstract: The feeder apparatus including a chamber formed of at least one upstanding wall, a water outlet in the wall, a drain in the wall, the chamber having a bottom, inlets for water jets in the bottom for creating turbulence inside the chamber to create particle suspension and/or to increase chemicals solubility, or a perforated plate inside of the chamber and spaced from the bottom of the chamber to permit water to flow underneath and up through perforations in the plate and into the chamber.

Abstract: A water purification apparatus connected to a water system includes a hopper for holding chemical tablets on a perforated bed and an underlying basin. A spray head is detachably connected to the perforated bed and sprays water onto the tablets and parallel to the perforated bed. The basin receives the water through the perforated bed. Because the hopper allows for the use of different spray head designs, the rate at which water is introduced to the tablets, and thus the chemical output, may be modified by replacing one spray head for another having a different number of spray nozzles or having spray nozzles of a different size or shape. Consequently, the hopper of the present invention may be used for delivering the proper concentration of a variety of water treatment chemicals.

Preferably, the microtiter plate is attached to one face of the one or more gaskets by an irreversible water-tight seal, and the first side of the one or more substrates is attached to the opposite face of the one or more gaskets by a reversible, water-tight seal.

Abstract: Disclosed are trichloroisocyanuric acid compositions that have improved algicidal and/or fungicidal properties yet are relatively safe and non-corrosive. The compositions preferably contain between about 50% and about 95% TCCA, between about 0.5% and about 7% glycoluril, between about 2% and about 40% alum, and between about 2% and about 40% borax. The compositions generate substantially less chlorine gas than would be expected from the teachings of the prior art, especially when wet. The inventive compositions are therefore less toxic and less corrosive.
