| 摘要 |
<p>The present invention provides methods, assays, kits, and components for the detection and analysis of binding between various biological or chemical species, as well as techniques for facilitating the attachment of various biological or chemical species to a particle. In some cases, particles having the ability to emit electromagnetic radiation within a narrow wavelength band, for example, semiconductor nanocrystals, are attached to a substrate or a structure, such as a molecule, a particle, a fluid sample, a cell, or a tissue. The attachment may be a direct attachment or an indirect attachment, for example, an attachment comprising an affinity tag/recognition entity interaction. The particles may then be further used to assay biological or chemical entities, or combined with other detection techniques.</p> |
