Abstract
The invention generally relates to fluorescent particles and more specifically to silica-based fluorescent nanoporous particles with physically encapsulated organic dyes. In one aspect of the invention, the nanoporous architecture provides a significant enhancement in fluorescence of the particles brightness compared to free dye. A particular chemical control of the silica matrix prevents the dye molecules from leaking the particles.
