Scalable methods, PRINT particle fabrication, and spray-assisted layer-by-layer deposition, are combined by Paula Hammond, Joseph DeSimone and co-workers on page 4707 to generate uniform and functional nanotechnologies with precise control over composition, size, shape, and surface functionality. A modular and tunable approach toward the design of built-to-order nanoparticle systems, spray coatings on PRINT particles are demonstrated to achieve technologies capable of targeted interactions with cancer cells for applications in drug delivery.
