Abstract: An optical element includes a porous layer with a network of a plurality of interconnected voids. The porous layer is optically diffusive to at least one wavelength of light when the network of interconnected voids is substantially free of fluid. The porous layer of the optical element undergoes a detectable optical change upon fluid ingress into the network or egress from the network of interconnected voids.

Abstract: A substantially planar self-folding film assembly to generate a folded three-dimensional assembly. The assembly includes a flexible support substrate, adhesive elements, and folding members. The folding members include a base, a folding region, and a hinge adjacent each folding region attached at the base to the flexible support substrate by at least one of the adhesive elements. An array of polymer actuators is co-extensive, or shaped to be not co-extensive, with each of the flexible folding members. Upon activation by a patterned light to heat conversion layer, each polymer actuator is designed and configured to provide a displacement of the corresponding flexible folding member about each hinge.

Abstract: A thin film culture device for enumerating mold colonies is provided. The device comprises water-resistant first and second substrates with a growth region disposed therebetween, a dry, cold water-soluble gelling agent disposed in the growth region, and an effective amount of a calcium-chelating compound disposed in the growth region. The effective amount of calcium-chelating compound is capable of reducing a rate of lateral enlargement of the colony-forming unit growing in the culture device relative to the rate of lateral enlargement of a colony of the same mold species growing in an otherwise identical culture device that does not contain the effective amount disposed in the growth region, wherein reducing the rate of lateral enlargement of the colony-forming unit does not substantially delay detection of the colony. A corresponding method is also provided.

Abstract: Three-dimensional polymeric article (100) having first (101) and second (102) opposed major surfaces, a base body (103) having a first dimension, a second dimension perpendicular to the first dimension, and a thickness, wherein the thickness is orthogonal to the first and second dimensions, wherein the base body (103) comprises a plurality of alternating, adjacent first (107) and second (108) polymeric regions along the first dimension, wherein the second dimensions of the first (107) and second (108) regions extend at least partially across the second dimensions, wherein the first regions (107) have a first crosslink density, wherein the second regions (108) have a second crosslink density, wherein the second crosslink density of the second regions (108) are less than the first crosslink density of the first regions (107), wherein the first and second regions extend perpendicularly in two directions from a central plane (115) in the base body (103) parallel to the first and second dimensions of the polymeric article (100), and wherein the second regions (108) extend in each of said two directions further than does the first regions (107). Embodiments of the three-dimensional polymeric article described herein are useful for providing a dual sided, textured wrapping film such that greater grip is realized both on an item wrapped by the film and the wrapped item itself.

Abstract: Method for detecting an analyte of interest in a sample. The method can include providing a container including a microstructured surface, and centrifuging the container toward the microstructured surface to form a sediment and a supernatant of the sample. Following centrifugation, the container can be inverted to decant at least a portion of the supernatant of the sample from the second portion, such that a concentrate (e.g., including the sediment) of the sample is retained in the microstructured surface. The concentrate can then be interrogated in the microstructured surface for the analyte of interest. In some embodiments, at least a portion of the second portion can be substantially transparent, such that the concentrate can be interrogated from the outside of the container, without requiring that the container be opened prior to interrogation.

Abstract: The present invention provides method of detecting a predetermined biological activity. The method includes using an aqueous mixture comprising a first indicator reagent with a first absorption spectrum and a second indicator reagent. The second indicator reagent is converted by the predetermined biological activity to a second biological derivative with a second emission spectrum. The first absorbance spectrum includes detectable absorbance in at least a portion of wavelengths present in the second emission spectrum. The first indicator reagent is received and concentrated from an aqueous liquid by a substrate, facilitating the detection of the second biological derivative.
