Abstract: Biosensors are disclosed based on one- or two-dimensional photonic-crystal reflectance filters operating at near-ultraviolet wavelengths. The biosensors feature a tightly confined resonant electric field at the surface of this biosensor and provide a high surface-sensitivity to bulk-sensitivity ratio, and therefore enables enhanced detection resolution for biomolecules adsorbed on the biosensor surface. These new biosensors can be fabricated in mass by replica molding. They are especially well suited for applications requiring the detection of small molecules or ultra-low analyte concentrations.

Abstract: Disclosed are embodiments of airflow applicators used for delivering directional, heated air to, for example, the scalp and hair of humans and/or animals to eliminate ectoparasites, such as lice and lice eggs. In preferred embodiments, the applicators are configured to deliver heated airflow (from a separate device, or from another portion of a single device, that generates heated airflow) efficiently right to where ectoparasites and their eggs most frequently reside. Also disclosed are treatment methods, including preferred treatment patterns, for delivering heated airflows for use in eliminating ectoparasites and their eggs on an animal.

Abstract: Enhancement of fluorescence emission from fluorophores bound to a sample and present on the surface of two-dimensional photonic crystals is described. The enhancement of fluorescence is achieved by the combination of high intensity near-fields and strong coherent scattering effects, attributed to leaky photonic crystal eigenmodes (resonance modes). The photonic crystal simultaneously exhibits resonance modes which overlap both the absorption and emission wavelengths of the fluorophore. A significant enhancement in fluorescence intensity from the fluorophores on the photonic crystal surface is demonstrated.

Abstract: A freeze-dried material is stored in a first chamber of a container along with a reconstituting liquid for the freeze-dried material, which is stored in a second chamber of the container. A sealing wall within the container forms a barrier between the first chamber and the second chamber preventing contact between the freeze-dried material and the reconstituting liquid. At least one valve assembly in the sealing wall selectively opens a region of the sealing wall to establish fluid flow communication between the first and second chambers, allowing the freeze dried material to be reconstituted. The reconstituted freeze-dried material can be administered from the same container to a recipient.

Abstract: A vessel receives a liquid material, which is freeze-dried in situ within the vessel. A gas permeable material carried by the vessel provides gas transport for sublimation during drying. After freeze drying, an oxygen-free inert gas is introduced into the vessel through the gas permeable material, to occupy the interior of the vessel with the freeze-dried material. The gas permeable material is covered, to trap the oxygen-free inert gas within the vessel with the freeze-dried material. The freeze-dried material is stored in the entrapped oxygen-free inert gas within the vessel for a storage period. The vessel receives a reconstituting liquid for mixing with the freeze-dried material, and conveys the reconstituted freeze-dried material from the vessel for administration to an individual.

Abstract: A medical suspension system (10) includes a ceiling plate (30) configured for mounting to a support structure (16). The ceiling plate supports a device (12), such as a lighthead or video monitor, which is mounted to the ceiling plate via an articulated arm (50) and a spindle (40), which is centrally mounted to the ceiling plate. A second device (14) is mounted to the ceiling plate, not through the spindle (40), in the conventional manner, but via an adapter plate (62), which is mounted directly to the ceiling plate. This increases the number of devices which are readily carried by the support structure without extending the spindle length which conventionally occurs when additional hubs are added to the main spindle.
