A fingerprint imaging system is described comprising a film including an optically transparent self-wetting adhesive layer adhered to an imaging surface of an electronic optical image sensor. Also described is a method of use of an optical imaging system, and a film and multilayer film suitable for use with a fingerprint imaging system.

Fingerprint imaging systems comprising self-wetting adhesive, films and methods

Devices including a polydiorganosiloxane polyamide containing material having a microstructured surface are disclosed herein. Such devices can optionally include a flex circuit attached to the microstructured surface and can be useful, for example, in fluid handling applications.

Structured polydiorganosiloxane polyamide containing devices and methods

A sensorthat detects a chemical such as an organic vapor. The sensorincludes a film that has a film bodythat includes a detection layerand that is responsive to the presence of a chemical by providing a color change. The film also includes an occluding layerthat has a first major surfaceand that is bound to the film bodybut is inert to the detection layerto preclude the occluding layerand the chemical from causing a color change in the film bodyin an areanormal to the first major surfaceof the occluding layer. A sensor having this construction can provide a distinctly visible image on the sensor, which may be helpful in evaluating the remaining life of a filter cartridge.

Patterned chemical sensor having inert occluding layer

Herein are disclosed optoelectronic methods and devices for detecting the presence of an analyte. Such methods and devices may comprise at least one sensing element that is responsive to the presence of an analyte of interest and that may be interrogated optically by the use of at least one light source and at least one light detector.

Optoelectronic methods and devices for detection of analytes

A hardcoat composition comprises (a) one or more epoxy silane compounds, (b) one or more epoxy-functionalized perfluoropolyether acrylate oligomers, and (c) photoacid generator.

Epoxy-functionalized perfluoropolyether polyurethanes

Provided is a method of making microarrays that includes providing a substrate with discrete first microfeatures that have a first profile, and depositing vapor-coated materials onto the first microfeatures to form second microfeatures having a second profile that is substantially different from the first profile. Also provided is a method of adding a replication material to the vapor-coated microfeatures to form a mold. Microarrays made by this method can be used as substrates for surface-enhanced Raman spectroscopy (SERS).

Method of making microarrays

A method of obtaining a surface-enhanced optical property of an analyte using a flexible structured substrate having a metal layer conformably disposed on nanostructure, a flexible structured substrate, and a method of making the same.
