Claims20
An apparatus for analyzing gases in expired breath to assist in diagnosis of a medical condition, the apparatus comprising a nanosensor tuned to a specific concentration profile, to detect a particular gaseous analyte, wherein the presence and/or concentration of said gaseous analyte is indicative of a particular medical condition.
A method for utilizing a concentration profile in a breath sample to assist in the diagnosis of a medical condition, the method comprising:
- measuring the concentration profile of a particular gaseous analyte in said breath sample with a nanosensor comprising a sensing electrode containing unlabeled urea as a substrate tuned for measuring said particular gaseous analyte;
- and
- comparing the detected amounts of said gaseous analyte to a baseline to assist in diagnosis of a medical condition.
A method for determining biomolecule abundance, the method comprising:
- obtaining a breath sample having a plurality of biomolecules;
- and
- analyzing the sample utilizing an encapsulated sensor to determine whether a specific biomolecule in the sample matches a concentration profile of an analyte to which a nanosensor of the sensor tuned.
The method of claim 20, wherein the sensor can detect the specific biomolecule at a level of parts per billion.
