'Cornell dots' replace quantum dots for biological tagging, imaging and optical computing

User rating: not rated yet

CU dots bound to immunoglobin-G antibodies attach to the surface of leukemia cells, demonstrating a possible use in biological t
By surrounding fluorescent dyes with a protective silica shell, Cornell University researchers 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 Cornell nanoparticles offer an appealing alternative because of their greater chemical inertness and reduced cost.
