摘要： Monodisperse particles having: a single pure crystalline phase of a rare earth-containing lattice, a uniform three-dimensional size, and a uniform polyhedral morphology are disclosed. Due to their uniform size and shape, the monodisperse particles self assemble into superlattices. The particles may be luminescent particles such as down-converting phosphor particles and up-converting phosphors. The monodisperse particles of the invention have a rare earth-containing lattice which in one embodiment may be an yttrium-containing lattice or in another may be a lanthanide-containing lattice. The monodisperse particles may have different optical properties based on their composition, their size, and/or their morphology (or shape). Also disclosed is a combination of at least two types of monodisperse particles, where each type is a plurality of monodisperse particles having a single pure crystalline phase of a rare earth-containing lattice, a uniform three-dimensional size, and a uniform polyhedral morphology; and where the types of monodisperse particles differ from one another by composition, by size, or by morphology. In a preferred embodiment, the types of monodisperse particles have the same composition but different morphologies. Methods of making and methods of using the monodisperse particles are disclosed.

摘要： A testing system and test cartridge for analyzing a sample of water from a water source for specific analyte levels. The test cartridge including a membrane filter that captures a target analyte while allowing a labelled conjugate to permeate through the membrane. The conjugate includes an analyte-specific labelled binding reagent to bind with the target analyte for optical detection. The direct membrane interrogation (i.e., on-filter detection), determines analyte levels without elution of the analyte from a filter thereby improving analyte recovering and assay sensitivity.

摘要： There is disclosed a topical composition comprising at least one organic and/or inorganic phosphor in a physiologically acceptable medium, wherein the phosphor(s) is present in an amount effective to convert electromagnetic radiation of an initial frequency to a different frequency. In one embodiment, the phosphors convert the initial radiation frequency, such as infrared or visible light, to a higher frequency, such as ultraviolet (UV) radiation. In another embodiment, the phosphors convert the initial radiation from a higher frequency, such as UV radiation, to a lower frequency, such as infrared or visible light. Methods of treating keratinous material, such as the skin, hair, or lips, using the disclosed compositions are also disclosed.
