A composition can include a copper containing nanocrystal.

Light emitting nanocrystals and methods of making light emitting nanocrystals

The present invention provides compositions and methods for imaging tumor resections.

Methods and systems for spatially identifying abnormal cells

A semiconductor nanocrystal can be made by an in situ redox reaction between an M donor and an E donor.

Scalable and safe nanocrystal precursor

A method and system for medical imaging employs an excitation source configured to cause an object having a plurality of cells to at least one of emit, reflect, and fluoresce light. An optical receptor is employed that is configured to receive the light from the object. A filter assembly receives the light from the optical receptor and filters the light. An image processor having a field of view (FOV) substantially greater than a diameter of a cell of the object and an analysis resolution substantially matched to the diameter of a cell of the object that receives the filtered light from the filter and analyzes the filtered light corresponding to each cell in the FOV. A feedback system is provided that is configured to provide an indication of a state of each cell in the FOV and a location of a cell in the FOV meeting a predetermined condition.

System and method for large field of view, single cell analysis

Systems and methods for measuring short wave infrared fluorescence and autofluorescent signals are disclosed. In some embodiments, for example, a method may include exposing a portion of tissue that does not include a fluorescent probe to an excitation source of the tissue, wherein at least a portion of the tissue has an autofluorescence spectrum which includes wavelengths greater than 900 nm, and imaging the tissue with a detector that is sensitive to electromagnetic radiation with wavelengths greater than or equal to 900 nm. In certain other embodiments, a system comprises a fluorescent probe including a fluorescent component attached to a carrier, an excitation source, and a detector that detects a tail portion of the fluorescence of the fluorescent component. Methods associated with such a system are also disclosed.

Device and method for imaging shortwave infrared fluorescence

InAs based core-shell particles which leads to tunable, narrow emitting semiconductor nanocrystals with a very high quantum yield which can be preserved in physiological buffers with long stability can used for short wavelength infrared (SWIR) imaging. Increased resolution with reduced read time and increased imaging frequency can provide advantages in in vivo applications.

Short-wavelength infrared (SWIR) fluorescence in vivo and intravital imaging with semiconductor nanocrystals

Systems and methods for measuring short wave infrared fluorescence and autofluorescent signals are disclosed.

Multifunctional nanoparticles can include two or more different populations of nanocrystals that impart a combination of properties arising from the constituent populations in a single, multifunctional nanoparticle.

Multifunctional nanoparticles

A method of making a nanocrystal includes slowly infusing a M-containing compound and a X donor into a mixture including a nanocrystal core, thereby forming an overcoating including M and X on the core.

Semiconductor nanocrystals

The present invention generally relates to composition and methods for downconverting light. In some embodiments, the composition and methods comprise an organic material, a nanocrystal, and a ligand capable of facilitating energy transfer between the organic material and the nanocrystal. In certain embodiments, the nanocrystal has a first excited energy state with an energy less than a triplet energy state of the organic material. The organic material, in some embodiments, may be aromatic and/or include one or more pi-conjugated carbon-carbon double bonds. In some cases, incident light may be absorbed by the organic material to produce two triplet excitons. The triplet excitons may then transfer to the nanocrystal via the ligand, where they can undergo recombination, resulting in the formation low energy photons.

Compositions and methods for the downconversion of light

A method of preparing a coated nanoparticle can include decomposing a compound to produce a nanoparticle, oxidizing the nanoparticle to produce an oxidized nanoparticle, and coating the oxidized nanoparticle with a zwitterionic ligand to produce the coated nanoparticle. The coated nanoparticle or the nanoparticle can be used in magnetic resonance imaging.

Nanoparticles for magnetic resonance imaging applications

A nanocrystal composition can include a nanocrystal and an outer layer including a ligand bound to the nanocrystal, wherein the ligand includes a norbornene group and a carboxyl group.

Synthesis of nanocrystals

A light emitting device can include a light source, a first electrode, a second electrode, a first barrier layer, a second barrier layer, and an emitter layer between the first barrier layer and the second barrier layer. A method of controllably generating light can comprise two states: An ON state, wherein an emitter layer of a device (which includes a photoluminescent pixel) is illuminated with a light source in the absence of an electric field, and the emitter layer generates light through photoluminescence; and an OFF state, wherein an emitter layer of a device (which includes a photoluminescent pixel) is illuminated with a light source in the presence of a static or time-varying electric field, and the electric field or induced current results in quenching of the emitter photoluminescence.

Transparent luminescent displays enabled by electric-field-induced quenching of photoluminescent pixels
