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.
