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%.
提供了形成染色微球的各种方法。一种方法包括使用热或光激活与染料耦合的化学结构,在微球存在的情况下形成反应中间体。反应中间体与微球的聚合物共价连接,从而将染料与聚合物偶联,形成染色微球。还提供了形成与分子偶联的染色微球的其他方法。这些方法除了在染色微球的外表面合成分子外,还包括如上所述对微球进行染色。还提供了染色微球群。群体中的每个染色微球都包括通过化学结构附着在每个染色微球的聚合物上的染料。可归因于染料的染色微球群体的染料特性变异系数小于约 10%。
