Based on previous experimental results, we present a droplet-based microfluidic platform for cell lysis, which integrates a) passive cell encapsulation, b) mixing the microdroplet content, and c) the cell lysis. Microdroplets are produced continuously by pumping fluids (Fluorinert oil and assay buffer containing detergent Triton-X) from external pressure-driven reservoirs. Hela cells in assay buffer stained with Propidium iodine are passively encapsulated into the droplets. Further, the droplet content is mixed and the cells are lysed in the incubation part of the chip. The lysed cells are indicated by red fluorescence. Single-cell
lysates will be mixed with photon-upconversion nanoparticles forming immunochemical complexes, and will be analyzed by massively parallel spectroscopy without separating, washing, and other common steps of
immunochemical assays.
