Abstract
The invention generally relates to mass tag analysis for rare cells and cell free molecules. In certain embodiments, the invention provides an apparatus including an essentially non-absorbent membrane having at least one pore, a microwell operably associated with the essentially non-absorbent membrane, and an electric field generator. The apparatus may be configured such that an electric field produced by the electric field generator operably interacts with a sample in the microwell and expels a droplet of the sample through the at least one pore in the essentially non-absorbent membrane. In certain embodiments, apparatuses of the invention are used for detection, and optionally quantification, of a target analyte from a heterogeneous sample, such as a rare target analyte (e.g., rare cell) from a biological sample.
