1. A breath analyzer, comprising:
- at least a first nanoelectronic sensor, the sensor including a substrate;
one or more nanostructures disposed over the substrate;
one or more conducting elements in electrical communication with the nanostructure; and
at least one recognition material operatively associated with the first nanostructure, the at least one recognition material configured to provide a sensitivity to a first analyte found in human breath;
a breath sampler configured to sample at least the exhaled breath of a patient, and in communication with the sensor;
a processing unit configured to receive a signal from the first sensor and to use the signal to measure the concentration of the first analyte, so as to provide information related to a medical state of the patient.

Abstract
Nanoelectronic sensors, including sensors for detecting analytes such as CO2, NO, anesthesia gases, and the like in human breath. An integrated multivalent monitor system is described which permits two or more analytes to be measured in breath, for example to monitor pulmonary conditions such as asthma. The monitor system may be configured to be compact, light weight, inexpensive, and to include a microprocessor capable of both analyzing measurements to determine patient status, and storing measurement history. Wireless embodiments provide such enhancements as remote monitoring.
