A new vapor-phase method creates solvent-free amorphous organic nanoparticles in a single step, offering precise control over morphology and improved dissolution without additives or stabilizers.

Fig. 1: (a) Schematic of the OVPD process, (b) the regimes of OVPD growth. In OVPD, the organic compound is thermally evaporated into a diluting, non-reactive gas stream, and then transported in a hot ...
