Abstract: A method employs the addition of additive to increase the solubility of active ingredients in solution. Furthermore, a nanoparticle apparatus that uses inkjet dispenser is utilized to fabricate nanoparticles. The method comprises: (a) mixing a fenofibrate substance, an organic solvent and a solubility enhancing additive to form a saturated solution; and (b) spray-drying the saturated solution to form the nanoparticles containing fenofibrate, wherein the solubility enhancing additive comprises a surfactant or an excipient.

Abstract: A system for fabricating nanoparticles that includes a micro droplet sprayer, a device, and a drying chamber is disclosed. The micro droplet sprayer, such as an inkjet sprayer, composed of a tank, a channel, an actuator, and orifices is utilized for generation of micro droplets. The device is employed to provide the micro droplet sprayer with energy, thus, forcing droplets out. The droplets are dried in the drying chamber, obtaining nanoparticles.
