Abstract
Microbeads with embedded encode characteristics are of considerable interest due to their potential use in multiplexed bioassays, high-throughput screening and combinatorial chemistry. Lots of encoding strategies for tagging or labeling microbeads have arisen in the past couple of years. Compared with the organic dye counterparts, the ideal optical properties of quantum dots (QDs) (e.g. characteristic narrow and symmetric spectra, size-tunable emission and simultaneous excitation) make it possible to tag microbeads in a quantitative way. In this paper, quantitative doping of commercial polystyrene microbeads with single color quantum dots was reported. A detailed analysis of the optical characteristics of the QD-tagged microbeads was presented based on the combination of fluorescent spectroscopy and microscope imaging.
