Abstract: The present invention relates to methods, computer readable medium and systems for detecting and counting single nucleic acid molecules confined in nanoliter volumes using an unmodified camera, such as a cell phone camera. In particular, it identifies colorimetric amplification-indicator dyes that are compatible with the spectral sensitivity of standard mobile phones. The invention further provides an optimal ratiometric image-process for a selected dye to achieve a readout that is robust to lighting conditions and camera hardware and provides unambiguous quantitative results, even for colorblind users.

Abstract: A device for allowing compartmentalized reactions with minimized cross-contamination between the compartments, utilizing a delivery of material by loading wells to pooling wells, such that the pooling wells can be additively provided with reactants while maintaining isolation between the pooling wells. The use of geometric properties is used to facilitate transmission of fluids/droplets without the need for hydrophilic surfaces.
