荧光微球在比发射波长更短的光线照射下，会发出明亮和独特的颜色。相对于背景材料，这一特性提高了它们的对比度和可见度。除了传统微球的特点外，荧光产品还为分析方法提供了更好的灵敏度和可检测性。它们可以以水悬浮液或干粉的形式提供，在水介质或空气中的分散都是可能的，而不会降低其荧光特性。悬浮液的水介质是特殊配制的，以防止形成结块并保持长期稳定。它们可以在室温下储存。荧光微球可以用流式细胞仪、外照射显微镜、共聚焦显微镜、荧光分光光度计等检测。它们也可以用矿物灯或黑光灯检测，可以直接在被测试的基质或介质中观察，也可以将它们收集在膜过滤器上，用显微镜检查。在某些应用中，聚合物微球可以被溶解，并直接测量荧光染料。

AM公司介绍：


Applied Microspheres（埃德微）成立于 2011 年，位于荷兰莱顿市的中心，是 Distrilab Particle Technology 的关系企业。30 多年来，Distrilab 一直是欧洲粒子检测相关产品的主要供应商。
由于特定颗粒的产品的需求不断增长，以及多年来获得的丰富经验和专业知识，Applied Microspheres（埃德微）在德国美因茨建立了研究和生产中心。在过去的几十年中，使用可追溯到美国国家标准与技术研究院 (NIST) 标准的参考材料来验证和校准颗粒尺寸测量和颗粒计数仪器已成为普遍做法。随着对根据更多国际标准化程序 (ISO) 进行仪器校准和验证的需求不断增加，Applied Microspheres 开发了粒径标准和计数标准粒子，它们不仅可追溯至NIST，而且可追溯至 ISO 17025 认可实验室认证的参考材料。

This product line was developed for general laboratory use. Applied Microspheres can offer many batches of particles with a wide variety of diameters, that can be custom dyed with different fluorescent colours and intensity levels as required. The dyes are incorporated during the polymerisation process, which prevents dye leakage. Applied Microspheres’ unique technology ensures exceptionally small fluorescence C.V.’s. Dispersion in both aqueous media or air are possible without degradation of their fluorescent properties. They are available as aqueous suspensions or as dry powder. The aqueous medium for the suspensions is specially formulated to prevent the formation of agglomerates and for long-term stability. They can be stored at room temperature.

The fluorescent microspheres can be detected with a flow cytometer, epifluorescence microscope, confocal microscope, fluorescence spectrophotometer, amongst others. They can also be detected using a mineral light or black light and can be observed directly in the matrix or media being tested, or they can be collected on membrane filters for examination by microscope. For some applications, the polymer microspheres can be dissolved and the fluorescent dyes measured directly.

Typical applications include:
• Flow cytometry instrument calibration and set-up
• Fluorescence microscopy
• Fluorescent instrument monitoring
• Confocal microscopy reference particles
• Filtration media and systems testing
• Vial and container cleaning studies
• Flow tracing and fluid mechanics
• Centrifugation and sedimentation studies
