Please release me : Supercritical carbon dioxide was used as an antisolvent for the formation of nanoparticles that contain luciferin, a bioactive therapeutic, dispersed in poly(lactic acid) (PLA), a biodegradable polymer. These nanoparticles undergo slow and sustained drug release, which can be monitored by bioluminescence both in vitro and in vivo (see picture; ATP=adenosine triphosphate; ADP=adenosine diphosphate; Pi=inorganic phosphate).
