An optical device for sensing a presence of an analyte in a person includes a light source, an optical stack, and a reader. The light source emits a first light having a first wavelength. The optical stack is placed on the a skin of the person and includes a sensor material and an optical filter. The sensor material emits a second light having a second wavelength when irradiated with the first light. An optical property of the second light is sensitive to the presence of the analyte. The optical filter is disposed on the sensor material and includes at least ten microlayers. The optical filter has different first and second transmittances at the respective first and second wavelengths.

Optical stack, optical device and optical construction

Hydrophilic articles and methods of using such articles are described. The hydrophilic articles include a hydrophilic layer comprising sintered, acidified silica nanoparticles attached to a substrate. A spacer layer attached to a first portion of the hydrophilic layer defines at least one fluid transport channel bounded on one side by a second portion of the hydrophilic layer. The nanoparticles may include one or both of spherical and elongated nanoparticles.

Hydrophilic fluid transport device

Sample processing devices that include transmissive layers and control layers to reduce or eliminate cross-talk between process chambers in the processing device are disclosed. The transmissive layers may transmit significant portions of signal light and/or interrogation light while the control layers block significant portions of signal light and/or interrogation light. Methods of manufacturing processing devices that include transmissive layers and control layers are also disclosed. The methods may involve continuous forming processes including co-extrusion of materials to form the transmissive layer and control layer in a processing device, followed by formation of the process chambers in the control layer. Alternatively, the methods may involve extrusion of materials for the control layer, followed by formation of process chambers in the control layer.

Multilayer processing devices and methods

A system and method for preparing and collecting samples for analyte testing. The system can include a sample preparation system and a sample collection system coupled to the sample preparation system. The sample preparation system can include at least one of a deformable self-supporting receptacle comprising a reservoir and a freestanding receptacle comprising a reservoir. The reservoir can be adapted to contain a liquid composition. The sample collection system can be positioned in fluid communication with a reservoir of the sample preparation system, and can be adapted to capture an analyte of interest. The method can include providing a fluid path defined at least partially by the sample preparation system and the sample collection system, positioning the liquid composition in a reservoir of the sample preparation system, and moving at least a portion of the liquid composition in the fluid path to the sample collection system.
