摘要： Methods for detecting disease in a patient are disclosed. The methods involve administering to the patient a quantum dot-analyte conjugate, which includes an analyte that binds to a marker for the disease in the patient's gastrointestinal tract. The analyte is conjugated to a quantum dot having a characteristic emission wavelength. Using an endoscopic modality, a physician can illuminate portions of the patient's gastrointestinal tract and detect the presence of the marker based on emission of the quantum dot. Also disclosed are methods of predicting a response to a treatment in a patient.

摘要： A lighting fixture for promoting the development of animals comprises a backlight, such as an LED or an array of LEDs, and a series of one or more retractable, rotatable or interchangeable lenses comprising quantum dots, such that the color and/or color temperature of the light emitted by the lighting fixture can be altered and optimized during animal development. A lighting fixture adapted for use on an aquarium may be in the form factor of a standard fluorescent tube and comprise one or more LEDs and a quantum dot-containing film for down-converting at least a portion of the light emitted by the LEDs so as to provide optimum wavelengths for photosynthesis by aquarium plants while simultaneously providing attractive display lighting for the aquarium fish.

摘要： Light-emitting materials are made from a porous light-emitting semiconductor having quantum dots (QDs) disposed within the pores. According to some embodiments, the QDs have diameters that are essentially equal in size to the width of the pores. The QDs are formed in the pores by exposing the porous semiconductor to gaseous QD precursor compounds, which react within the pores to yield QDs. According to certain embodiments, the pore size limits the size of the QDs produced by the gas-phase reactions. The QDs absorb light emitted by the light-emitting semiconductor material and reemit light at a longer wavelength than the absorbed light, thereby “down-converting” light from the semiconductor material.

摘要： A method of preparing Group XIII selenide nanoparticles comprises reacting a Group XIII ion source with a selenol compound. The nanoparticles have an MxSey semiconductor core (where M is In or Ga) and an organic capping ligand attached to the core via a carbon-selenium bond. The selenol provides a source of selenium for incorporation into the semiconductor core and also provides the organic capping ligand. The nanoparticles are particularly suitable for solution-based methods of preparing semiconductor films.

摘要： Quantum dot (QD) LEDs useful for plant, algael and photosynthetic bacterial growth applications. The QD LEDs utilizes a solid state LED (typically emitting blue or UV light) as the primary light source and one or more QD elements as a secondary light source that down-converts the primary light. The emission profile of the QD LED can be tuned to correspond to the absorbance spectrum of one or more photosynthetic pigments of the organism.
