title: A selective nanosensor device for exhaled breath analysis.
abstract: This paper describes a novel concept of a three-nanosensor array microsystem that may potentially serve as a coarse diagnostic tool handheld breath analyzer to provide a first detection device. The specification and performance of a simple metal oxide nanosensor operating between three distinct temperatures are discussed, focusing on the need for a noninvasive blood cholesterol monitor. Interfacing the sensor array to an integrated circuit for electrical readout and temperature control provides a complete microsystem capable of capturing a single exhaled breath and analyzing it with respect to the relative content of isoprene, carbon dioxide and ammonia gas. This inexpensive sensor technology may be used as a personalized medical diagnostics tool in the near future.
