Quantum dots to be explored for use as fluorescent standards

“A fluorescence standard is necessary, especially for clinical applications, where quantification is required. It is nearly impossible to quantify the fluorescence from an assay today, but our collaboration with NIST should greatly advance the state of the art,” said Clint Ballinger, CEO, of Evident Technologies.

Gary Kramer from NIST said, “Traditional fluorescing materials, such as organic dyes, lose fluorescence intensity due to photodegradation and are ill-suited for use as standards. Evident's quantum dots are very promising in this application since they should be significantly more stable, an attribute required of a standard.”

Under the CRADA, Evident Technologies will provide quantum dot composites and NIST will be providing its expertise in fluorescent measurement to characterize these materials. Providing some of the first measurements on these new quantum dot composites and coatings, will help determine how this technology can be used to produce stable fluorescent standards.
