Flash NanoPrecipitation of CAI-1 nanoparticles. (A) Dynamic light scattering size distributions of CAI-1 NPs flashed with stabilizer, co-core, and CAI-1 (); of VitE NPs flashed with stabilizer and co-core (); and of empty micelles flashed with only stabilizer (). (B) Visual appearance of stabilizer micelles, VitE NPs, CAI-1 NPs, and CAI-1 in PBS. The CAI-1 in PBS is an oil that floats as a liquid drop on the water surface.
