摘要:
A self-contained drug screening apparatus, comprising a breath inlet component for receiving an exhaled air flow of a person, the exhaled air flow including saliva, and a sensor for sensing a presence of a drug in the saliva, and identification module for detecting an identifying characteristic of the person.
摘要:
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).
摘要:
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.
摘要:
A sensor 40 that detects a chemical such as an organic vapor. The sensor 40 includes a film that has a film body 58 that includes a detection layer 48 and that is responsive to the presence of a chemical by providing a color change. The film also includes an occluding layer 54 that has a first major surface 59 and that is bound to the film body 58 but is inert to the detection layer 48 to preclude the occluding layer 54 and the chemical from causing a color change in the film body 58 in an area 42 normal to the first major surface 59 of the occluding layer 54. 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.
摘要:
A phototool comprises an optically transparent substrate having designed pattern and a protective layer on the substrate. The protective layer comprises a cured hardcoat composition. The hardcoat composition comprises (i) one or more epoxy silane compounds (ii) one or more fluorochemical additives selected from the group consisting of perfluoropolyether-urethane silanes and silane-functionalized perfluoropolyether acrylate oligomers, and (iii) photo-acid generator.
