Conventional approaches to chemical sensors have traditionally made use of a “lock-and-
key” design, wherein a specific receptor is synthesized in order to strongly and highly …

There has recently been an explosion of interest in the analysis of breath constituents as a
way of monitoring inflammation and oxidative stress in the lungs. Here we review the use of …

The concept of using sensor arrays for chemical analysis gained widespread recognition in
the 1980s and has continued vigorously in the 1990s. The advantages that sensor arrays …

The analysis of organic vapors in exhaled breath can provide information about chemical
exposures and health status. This article describes work aimed at developing a small …

The combination of a tandem column ensemble and an on-line microsorption trap is used for
the analysis of organic compounds in human breath samples. The four-bed sorption trap …

Background The authors performed a prospective study to determine whether breath test
analysis using an electronic nose correlates with a clinical pneumonia score. Methods …

A comprehensive analysis of vapor recognition as a function of the number of sensors in a
vapor− sensor array is presented. Responses to 16 organic vapors collected from six …

Poly (3, 4-ethylenedioxy) thiophene− poly (styrene sulfonate)(PEDOT− PSS) was used as
the conductive component in a matrix of chemically different insulating polymers to form an …

A new generation of breath tests detects trace amounts of endogenous volatile organic
compounds (VOCs) present in the breath. The breath microanalysis is potentially fast and …

Arrays of vapor detectors have been formed through addition of varying mass fractions of the
plasticizer diethylene glycol dibenzoate to carbon black− polymer composites of poly (vinyl …
