Researchers show, for the first time, that it's possible to recycle the nanoparticles used in the creation of microscopic supraparticle lasers. Supraparticle lasers, which are used voice a variety of applications like drug delivery, sensing, and compact electronic systems, function through the suspension of costly quantum dots. This new method reduces costs and environmental impact by minimizing the need for new nanoparticles and the disposal of old ones, and it should be applicable to any colloidal nanoparticle species, especially rare-earth ones.
