Abstract
A microfluidic apparatus includes a microfluidic chip for MicroOrganoSpheres (MOS) generation. A first channel is defined in a surface of the microfluidic chip and includes: a droplet generation portion including an inlet portion, a junction between the inlet portion and an emulsifying fluid channel, and a chamber downstream of the junction. A cross-sectional area of the chamber is larger than that of the inlet portion. The first channel includes a polymerization portion downstream of the droplet generation portion, the polymerization portion having a serpentine configuration. The apparatus includes a cartridge for MOS demulsification, including: a collection container; a substrate disposed on the collection container, and a membrane disposed between the collection container and the surface of the substrate. A second channel is defined in the surface of the substrate that faces the collection container and is fluidically connected to an output of the polymerization portion of the first channel.
