摘要： Disclosed is a system and method for interrogating a photo-responsive material, such as for authentication purposes, utilizing a light source to illuminate a photo-responsive material, a detector to capture an emission from the photo-responsive material, and a processor to receive a response from the detector while the photo-responsive material is being illuminated after a maximum response has been received, then measuring a change in the received response.

摘要： This disclosure relates to a card having (i) an infrared-blocking material capable of blocking a plurality of near infrared wavelengths and (ii) at least one phosphor particle capable of absorbing at least one near-infrared wavelength, and a card reader capable of allowing a user to interrogate the card and determine if it is authentic, and to read information from the card. The card reader typically includes a processor configured to cause the card reader to emit at least one wavelength of light, receive at least one additional wavelength of light emitting by the at least one phosphor particle, and identify at least one characteristic of the at least one phosphor particle selected from the group consisting of a location on the card, a rise time of the phosphor, and a decay time of the phosphor.

摘要： A rapid diagnostic test strip, system, and methodology are disclosed. The test strips utilize a sample pad on a proximal portion of a substrate. When a sample (potentially containing various analytes) is provided to the sample pad, it is transported to a conjugate release pad located distally from the sample pad. The conjugate release pad includes two or more targeted materials, where each targeted material includes an upconverting rare-earth particle capable of conjugating to an analyte. The conjugated analytes are then transported distally along the test strip, where they may bind to one or more test lines. An absorbent pad is located distally from the test lines. The one or more test lines can the be briefly illuminated with one or more specific wavelengths of light that the rare-earth particles absorb, and the rare-earth particles then emit a response that can be detected and measured.

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.
