Abstract

In this study, colloidal crystal beads with controllable size, small-size dispersion, and good repeatability were fabricated. These beads have an optical stop-band and can be distinguished by their colors or spectra. Applications in genomics, proteomics, combinatorial chemistry, drug screening, and clinical diagnosis are anticipated.
