    • Customized therapeutics and in situ diagnostics for patient therapy and diagnosis takes advantage of tools including techniques for derivatizing colloids with self-assembled monolayers. This provides the capability of a wide variety of assays including chemical or biochemical agent/agent interaction studies. Bio-derivatized colloids, with or without signaling entities, are used to probe interactions with species on non-colloidal structures. The invention provides techniques for immobilizing colloidal particles on a wide variety of non-colloidal structures. Included is the ability to decorate a variety of non-colloidal structures including beads, with colloids as a detectable assay. This allows, in many cases, assays detectable via the unaided human eye, as well as assays detectable via automated determination of a change of interaction of electromagnetic radiation with the colloids, e.g., absorption, light-scattering, and the like.

    • The present invention discloses compositions and methods for enabling the long­term storage and/or use of colloid particles without substantial degradation of their performance, for example, by chemical or physical degradation, by particle aggregation, changes in pH and/or relative humidity, changes in salt concentration, and/or by a decrease in the binding activity or other detrimental change in biological, chemical, or physical properties of the colloid particles. In one aspect of the invention, the colloid particles are treated with an aggregation-preventing entity, for example, by immobilizing the entity relative to the colloid particle. In one embodiment, the aggregation-preventing entity forms at least a part of, and/or is immobilized relative to, a self-assembled monolayer ("SAM") immobilized to the colloid particle. The aggregation-preventing entity may be added to non-aggregated or aggregated particles, for example to prevent aggregation and/or to reduce the degree of aggregation. In some embodiments of the invention, the colloid particles are essentially free of surfactants and/or other non­ immobilized aggregation-preventing entities. The colloid particles and/or solutions thereof may be stored before use without substantial degradation or aggregation over long periods of time in a dried state and/or at low temperatures. After storage, certain colloid particles provided by the invention can remain substantially non-aggregated. Various colloid particles of the invention may be used in many techniques, for example, in gels or other assay systems. In some cases, the colloid particles have a high degree of specificity and/or activity, which is due, at least in part, to their ability to remain in a substantially non-aggregated and detergent-free state during storage and/or use.
    • 本发明公开了能够长期储存和/或使用胶体颗粒的组合物和方法,而不会通过化学或物理降解,通过颗粒聚集,pH和/或相对湿度的变化, 盐浓度,和/或通过胶体颗粒的生物学,化学或物理性质的结合活性或其它有害变化的降低。 在本发明的一个方面,胶体颗粒用聚集防止实体进行处理,例如通过相对于胶体颗粒固定该实体。 在一个实施方案中,聚集防止实体相对于固定在胶体颗粒上的自组装单层(“SAM”)形成至少一部分和/或固定。 可以将聚集防止实体添加到非聚集或聚集的颗粒,例如以防止聚集和/或降低聚集度。 在本发明的一些实施方案中,胶体颗粒基本上不含表面活性剂和/或其它非固定的聚集防止物质。 胶体颗粒和/或其溶液可以在使用前储存,在干燥状态和/或低温下长时间不会显着降解或聚集。 储存后,本发明提供的某些胶体颗粒可以保持基本上不聚集。 本发明的各种胶体颗粒可用于许多技术中,例如在凝胶或其它测定系统中。 在一些情况下,胶体颗粒具有高度的特异性和/或活性,其至少部分是由于其在储存和/或使用期间保持基本上非聚集和无去污剂状态的能力。

    • 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.
