Cornell Produces Brighter Dots
May 20, 2005 — ITHACA, N.Y., May 20 -- By surrounding fluorescent dyes with a protective silica shell, Cornell University researchers announced this week they have created fluorescent nanoparticles with possible applications in displays, biological imaging, optical computing, sensors and microarrays such as DNA chips. These are all applications for which quantum dots have been used or are being considered. But the new nanoparticles offer an appealing alternative, because they are more chemically inert and...
