    摘要： Precisely-shaped composites and methods for making these composites are disclosed. The method of this disclosure comprises introducing a precursor composition onto a production tool having at least one continuous surface and a plurality of cavities so as to fill at least a portion of the cavities with the precursor composition and wherein the precursor composition, upon curing, forms a composition having a shape corresponding to the cavities thereby resulting in a plurality of discrete, precisely-shaped particles having a porosity comprising one of the following: (a) 10 m2/g or greater or (b) 5 kdalton or greater. The precisely-shaped particles have at least one essentially flat side. The precisely-shaped particles can be confined in a vessel and used for chromatographic applications.

    摘要： A device for culturing microorganisms and its use are described. The claimed device comprises a substrate having a top side, a pedestal mounted on the top side of the substrate and comprising a non-absorbent culture surface, a flexible cover sheet attached to the substrate and comprising a bottom surface, the cover sheet being configured to cover the culture surface, and a culture medium deposited on one or more surfaces selected from: the culture surface, and the cover sheet bottom surface. An aqueous sample is spread and contained by the claimed device without additional equipment or manipulation by the end user.

    摘要： Disc assay devices and methods for the detection and enumeration of microorganisms are disclosed. The devices and methods include a plurality of discs attached to a substrate and a reflector on one surface of each of the discs to reflect electromagnetic energy of selected wavelengths after the energy has passed through the disc. The reflector may be useful to improve the accuracy of detection and/or enumeration of target microorganisms on the assay devices. A system for detecting and/or enumerating target microorganisms on disc assay devices is also provided.
