A microfluidic origami chip for synthesis of functionalized polymeric nanoparticles

This report demonstrates a microfluidic origami chip to synthesize monodisperse, doxorubicin-loaded poly(lactic-co-glycolic acid) nanoparticles with diameters of ~100 nm, a size optimized for cellular uptake and anticancer efficacy, but difficult to achieve with existing approaches. This three-dimensional design in a microchannel may allow for the fabrication of polymeric nanoparticles in this size regime with ease.
