Embodiments described herein provide devices and methods for the determination of analytes. The device typically includes an absorbent material that allows for an analyte sample to be concentrated and analyzed simultaneously and within a short period of time (e.g., less than 10 seconds). Embodiments described herein can provide portable and easily operable devices for on-site, real time field monitoring with high sensitivity, selectivity, and fast response time.

Devices and methods including a preconcentrator material for detection of analytes

A sensor device can include a transition metal complex capable of interacting with a carbon-carbon multiple bond moiety. The sensor can detect the fruit-ripening hormone ethylene with high sensitivity.

Ethylene sensor

Components, systems, and methods for gas sensing identification are generally disclosed. In some embodiments, a characteristic of an article (e.g., identity, authenticity, property, product associated information such as age or quality, etc.) may be determined by determining the presence (e.g., an amount) or absence of a chemical compound (or compounds) emanating from the article. For example, the presence or absence of the compound (or compounds) emanating from the article identifies a characteristic of the article. In some embodiments, the chemical compound(s) has been proactively added to the article. That is to say, in some embodiments, the chemical compound is not inherently associated with the article but is added in order to, for example, identify a characteristic of the article.

Gas sensing identification

A sensor can include a conductive region in electrical communication with at least two electrodes, the conductive region including a conductive material and an alkene-interacting metal complex.

Gas sensors based upon metal carbon complexes

Methods described herein may be useful in the fabrication and/or screening of devices (e.g., sensors, circuits, etc.) including conductive materials. In some embodiments, a conductive material is formed on a substrate using mechanical abrasion. The methods described herein may be useful in fabricating sensors, circuits, tags for remotely-monitored sensors or human/object labeling and tracking, among other devices. In some cases, devices for determining analytes are also provided.

Methods for deposition of materials including mechanical abrasion

The present invention generally provides compositions including carbon-based nanostructures, catalyst materials and systems, and related methods. In some cases, the present invention relates to carbon-based nanostructures comprising a high density of charged moieties. Methods of the invention may provide the ability to introduce a wide range of charged moieties to carbon-based nanostructures. The present invention may provide a facile and modular approach to synthesizing molecules that may be useful in various applications including sensors, catalysts, and electrodes.
