UT-Battelle Licenses AB-Sciex ORNL Inventions Government facilities in Oak Ridge Tennessee have a 60 year long history in mass spectrometry, beginning with the Calutrons used for isotope separation during the 1940's. Today Oak Ridge National Laboratory (ORNL) has one of the largest, most diverse and highly recognized mass spectrometry programs in the world, carrying out fundamental research, inst…

Internal Labeling Technique Tracks Nanoparticle Transport To track the transport of nanoscale particles and core-shell particles in biological and environmental systems, ORNL researchers developed a way to insert a radioisotope or a fluorophore into the particle as an observable marker. Internalized labeling of nanoparticles leaves the surface intact and available for functionalization with a h…
