Abstract: The disclosed invention provides a biofluid collection device configured with a hexagonal open microfluidic network, which facilitates nanoliter-scale biofluid collection and transport for biosensing applications. In one embodiment, a biofluid sensing device placed on the skin for measuring a characteristic of an analyte in sweat includes one or more biofluid sensors and a hexagonal open microfluidic network biofluid collector. The disclosed collector provides a volume-reduced pathway for sweat biofluid between the one or more sensors and sweat glands when the device is positioned on the skin. In another embodiment, a biofluid collector includes a network of microchannels comprising three or more repeatedly intersecting channels that provide redundant pathways for biofluid transport.

Abstract: We describe a method of layer-by-layer deposition of a plurality of layers of material onto the wall or walls of a channel of a microfluidic device, the method comprising: loading a tube with a series of segments of solution, a said segment of solution bearing a material to be deposited; coupling said tube to said microfluidic device; and injecting said segments of solution into said microfluidic device such that said segments of solution pass, in turn, through said channel depositing successive layers of material to perform said layer-by-layer deposition onto said wall or walls of said channel. Embodiments of the methods are particularly useful for automated surface modification of plastic, for example PDMS (Poly(dimethylsiloxane)), microchannels. We also describe methods and apparatus for forming double-emulsions.

Abstract: To provide a plate with which, although the plate has a plurality of microchannels or a microchannel in which a plurality of branch channels are formed, when a sample flowing through a microchannel is observed by a microscope, it is possible to easily identify the position of the microchannel or the branch channel under observation without reducing the magnification of the microscope.
A plate having a microchannel therein includes an identification mark for identifying a position of the microchannel in a plane direction of the plate. When the microchannel includes a plurality of mutually independent microchannels, the identification mark is preferably formed for each microchannel. When the microchannel includes a source channel communicating with an injection port through which a sample is injected and a plurality of branch channels communicating with the source channel, the identification mark is preferably formed for each of the source channel and the branch channels.-
