الوصف: | We present a simple, bottom up method for the structural design of solid microparticles containing crystalline drug and excipient using microfluidic droplet-based processing. In a model system comprising 5-methyl-2-[(2-nitrophenyl)amino]-3-thiophenecarbonitrile (ROY) as the drug and ethyl cellulose (EC) as the excipient, we demonstrate a diversity of particle structures, with exquisite control over the structural outcome at the single-particle level. Within microfluidic droplets containing drug and excipient, tuning droplet composition and solvent removal rates allows us to controllably access structural diversity via an interplay of three physical processes (liquid–liquid phase separation, drug crystallization, and polymer vitrification) occurring during solvent removal. Specifically, we demonstrate two levels of structural control—a coarse “macro” particle structure and a finer “micro” structure. Further, we elucidate the key mechanistic elements responsible for the observed structural diversity using a... |
