ASSAY DEVICES THAT UTILIZE HOLLOW PARTICLES

摘要

Hollow particles for use in various types of assay devices are provided. Due to their hollow or voided structure, the particles may exhibit a variety of beneficial properties. For instance, hollow particles are generally lightweight, and thus, relatively inexpensive in comparison to other types o f particles. Hollow particles may also form a stable system without requiring refrigeration or rotation. In addition, hollow particles may possess enhance d light diffraction capabilities, which may be particularly beneficial in certain types of assay devices, e.g., diffraction-based assay devices.
