Abstract
Devices to detect a substance and methods of producing such a device are disclosed. An example device to detect a substance includes a housing defining a first chamber and a substrate coupled to the housing. The substrate includes nanostructures positioned within the first chamber. The nanostructures are to react to the substance when exposed thereto. The device includes a first heater positioned within the first chamber. The heater is to heat at least a portion of the substance to ready the device for analysis.
Claims20
A device to detect a substance, comprising:
- a housing defining a first chamber;
- a substrate coupled to the housing, the substrate comprising nanostructures positioned within the first chamber, the nanostructures to react to the substance when exposed thereto, wherein the nanostructures comprise pillars having ends that close together in response to evaporation of the substance;
- and
- a first heater positioned within the first chamber, the heater to heat at least a portion of the substance to evaporate the substance to ready the device for analysis.
A device to detect a substance, comprising:
- a housing defining a chamber;
- a substrate coupled to the housing, the substrate comprising nanostructures positioned within the chamber, the nanostructures to react to the substance when exposed thereto;
- a sensor positioned within the chamber, the sensor to measure a parameter value of the substance, the sensor different than the nanostructures;
- and
- a bore through the housing opposite the substrate and opposite the nanostructures.
