Microcapsules and microparticles are industrially used to protect and deliver active materials, such as drugs in medication, fragrances in creams and aromas in food. Today’s microencapsulated materials have neither control in actual particle size nor in their size distribution. Hence, the final products often have unknown release profiles, poor dosage control, and a decreased stability over time. Until today, state-of-art microfluidic techniques only work with very little volumes as they lack scalability and stability. Therefore, a trade-off between large production volumes and monodispersity has to be found. However, with Microcaps this trade-off is resolved, our technique enables laboratory Swiss precision at industrial scale. Large production volumes of size-controlled (monodisperse) microparticles,-emulsions, and -capsules, are now possible by upscaled microfluidics. Moreover, our emulsification platform has the advantage of being highly flexible (10 to 2000µm particle size) and adaptable (chemical components and batch sizes) , as well as being robust and cost-effective.
