    摘要： Various methods for forming dyed microspheres are provided. One method includes activating a chemical structure coupled to a dye using heat or light to form a reaction intermediate in the presence of a microsphere. The reaction intermediate covalently attaches to a polymer of the microsphere thereby coupling the dye to the polymer and forming the dyed microsphere. Additional methods are provided for forming a dyed microsphere coupled to a molecule. These methods include dyeing the microspheres as described above in addition to synthesizing the molecule on an outer surface of the dyed microspheres. A population of dyed microspheres is also provided. Each of the dyed microspheres of the population includes a dye attached to a polymer of each of the dyed microspheres by a chemical structure. A coefficient of variation in dye characteristics of the population of dyed microspheres attributable to the dye is less than about 10%.

    摘要： A method for altering fluorescent emissions of particles includes setting the particles in motion and exposing the moving particles to light such that fluorescent intensities of the particles are lessened isotropically and substantially simultaneously. Another method includes measuring fluorescent emissions of particles, determining the measured fluorescent emissions do not collectively fit within a first predetermined range of fluorescent values, and exposing the particles to one or more incidents of light that are configured to cooperatively alter the fluorescent emissions of the particles to be within a second predetermined range of fluorescent values. An embodiment of an apparatus includes a vessel configured to contain a plurality of particles and a means for setting the particles in motion. The apparatus further includes an illumination subsystem configured to direct light toward the vessel and at a spectral window (i.e., wavelength or band of wavelengths) which is configured to isotropically and substantially simultaneously lessen the fluorescent emissions of each of the particles.

    摘要： Various methods for forming dyed microspheres are provided. One method includes attaching a hydrophilic dye to chemical groups to form a bubble. The bubble includes the chemical groups surrounding the hydrophilic dye and an aqueous solution. The chemical groups are soluble in aqueous and organic solvents. The method also includes disposing the bubble and a microsphere to be dyed in a solvent such that the bubble is incorporated into the microsphere thereby dyeing the microsphere. Another method includes adsorbing a hydrophilic dye on a surface of a hydrophobic polymer core of a microsphere to be dyed thereby dyeing the microsphere. The method also includes attaching chemical groups to the hydrophilic dye. The chemical groups are soluble in aqueous and organic solvents. The chemical groups attached to the hydrophilic dye form an enclosure surrounding the hydrophilic dye and an aqueous solution.
