A New Nanoparticle Design for Imaging with Ultralow Powers of Near Infrared Light


Scientific Achievement

Foundry staff and users have developed alloyed upconverting nanoparticles (UCNPs) that can be excited with low-powered lasers for sensitive and non-toxic imaging. 

Significance and Impact

The nanocrystals can be imaged with low-energy light at laser intensities over 300-fold lower than needed for previous comparably sized UCNPs, leading to advanced imaging of light-sensitive systems, such as high-precision surgeries.
