This invention provides a novel fluorescent particle including a core or carrier particle having on its surface a plurality of smaller polymeric particles or nanoparticles, which are stained with different fluorescent dyes. When excited by a light source they are capable of giving off multiple fluorescent emissions simultaneously, which is useful for multiplexed analysis of a plurality of analytes in a sample. The coupled complex particles carrying on their surface fluorescent nanoparticles, methods of preparing such polymer particles, and various applications and methods of using such particles are claimed.
本发明提供了一种新型荧光颗粒,包括一个核心或载体颗粒,其表面有多个较小的聚合物颗粒或纳米颗粒,这些颗粒被不同的荧光
染料染色。当被光源激发时,它们能够同时发出多种荧光,这有助于对样品中的多种分析物进行多重分析。本发明提出了在其表面携带荧光纳米粒子的耦合复合粒子、制备这种聚合物粒子的方法以及使用这种粒子的各种应用和方法。
