The purpose of the present invention is to provide a novel digital PCR analysis method. In the digital PCR analysis method disclosed herein, a method for detecting DNA is used, which includes the steps of: dividing a DNA solution containing a fluorescent-labeled probe or a DNA intercalator and a plurality of DNAs to be detected into a plurality of compartments; carrying out PCR in the compartments; measuring a fluorescence intensity in association with a change in temperature; calculating a melting temperature from a melting curve for a DNA double strand measured on the basis of a change in fluorescence intensity, which is associated with the change in temperature; and calculating a temperature difference between two points with a slope of a predetermined value on a melting curve indicating a change in the fluorescence intensity.

The invention provides devices that improve tests for detecting specific cellular, viral, and molecular targets in clinical, industrial, or environmental samples. The invention permits efficient detection of individual microscopic targets at low magnification for highly sensitive testing. The invention does not require washing steps and thus allows sensitive and specific detection while simplifying manual operation and lowering costs and complexity in automated operation. In short, the invention provides devices that can deliver rapid, accurate, and quantitative, easy-to-use, and cost-effective tests.

A biological fluid analysis cartridge is provided. In certain embodiments, the cartridge includes a base plate extending between a sample handling portion and an analysis chamber portion. A handling upper panel is attached to the base plate within the sample handling portion. A collection port is at least partially formed with the handling upper panel. An initial channel and a secondary channel are formed between the handling upper panel and the base plate. The collection port and initial and secondary channels are in fluid communication with one another. A chamber upper panel is attached to the base plate within the analysis chamber portion. At least one analysis chamber is formed between the chamber upper panel and the base plate. The secondary channel and the analysis chamber are in fluid communication with one another.

An analytical toilet comprising a bowl for receiving excreta from a user; a base supporting the bowl; a supply of flush water; and a plurality of receptacles, each providing mechanical attachment, a power supply, and a data connection to an analytical device, which analytical device is adapted to provide data useful to the user is disclosed.

A multi-layered microfluidic system featuring tissue chambers for cells in a first layer and a plurality of medium channels for culture medium in a second layer. The tissue chambers fluidly connect to the medium channels such that media flows from the medium channels to the tissue chambers, forming large-scale perfused capillary networks. The capillary networks can undergo angiogenesis and vertical anastomosis. The multi-layered configuration of the system of the present invention allows for flexibility in design.
