  • COMPOSITE PARTICLES FOR BIOLOGIC ASSAY
    Publication number: 20230194514
    Abstract: Composite particles including nanoparticles dispersed in a matrix and their use in biologic assay. The nanoparticles selectively absorb or selectively emit light and have a size in at least one of its dimensions shorter than 20 nm. The weight fraction of the nanoparticles in the composite particles is greater than 0.5% and less than 50%, and the matrix of the composite particles is inorganic and includes less than 90% by weight of silica. Also, the composite particles are functionalized with a specific-binding component and have a mean size greater than 50 nm and less than 1000 nm.
