    摘要: A novel encoding system, compositions for use therein and methods for determining the source, location and/or identity of a particular item or component of interest is provided. In particular, the present invention utilizes a collection of one or more sizes of populations of semiconductor nanocrystals having characteristic spectral emissions, to “track” the source or location of an item of interest or to identify a particular item of interest. The semiconductor nanocrystals used in the inventive compositions can be selected to emit a desired wavelength to produce a characteristic spectral emission in narrow spectral widths, and with a symmetric, nearly Gaussian line shape, by changing the composition and size of the semiconductor nanocrystal. Additionally, the intensity of the emission at a particular characteristic wavelength can also be varied, thus enabling the use of binary or higher order encoding schemes.

    摘要: The present invention generally relates to lasers comprising fluidic channels, such as microfluidic channels. In some instances, the channel contains two or more fluids. The fluids may remain non-mixed within the channel, for example, due to immiscibility and/or laminar flow within the channel. The fluids may be arranged in the channel such that light propagating in a first fluid is prevented by the second fluid from exiting the first fluid, for example, due to differences in the indexes of refraction (e.g., causing internal reflection of the fluid to occur). Thus, in one embodiment, a first fluid may be at least partially surrounded by a second fluid having a second index of refraction lower than the index of refraction of the first fluid. In some embodiments, the fluidic channel is used as a laser, for instance, a dye laser, i.e., a laser created by directing light at a dye to produce coherent light. The dye may be present in one or more fluids within the fluidic channel. The incident light (for example, created by another laser) may be directed at the channel from any angle. In some cases, laser light may be produced in a direction substantially aligned with the longitudinal axis of the channel. In some embodiments, the laser is free of mirrors, prisms, or gratings, or the laser may produce coherent light using a non-resonant photonic pathway. However, in other cases, mirrors, prisms, or gratings may be used to reflect light along the channel to enhance stimulated emission of coherent light. Another aspect of the invention includes optical diffractors, such as prisms or gratings, which can contain a fluid. The optical diffractors, in certain embodiments, are positioned to diffract light, such as coherent light, emanating from the fluidic channel. Still other aspects of the invention provide devices, kits, and methods of making and using such lasers.

    摘要: 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.
