Since the first suggestion, during the 1950s, that high-surface-area metal oxides could be
used as conductometric gas sensors enormous efforts have been made to enhance both the …

Conspectus As a futuristic diagnosis platform, breath analysis is gaining much attention
because it is a noninvasive, simple, and low cost diagnostic method. Very promising clinical …

Volatile organic compounds (VOCs) are present in the mixture of gases found in the exhaled
human breath. Since their occurrence in the breath may indicate the presence of a disease …

A novel chemiresistive-type sensor for detecting sub-ppm NO2 has been fabricated using
AuPt bimetal-decorated SnSe2 microflowers, which was synthesized by the hydrothermal …

Finding a non-invasive, painless and simple method for monitoring of health parameters and
early detection of physiological disorders is of utmost importance in today's world. Breath …

Highly sensitive sensors to detect small amounts of gases are expected to be used for
monitoring air quality and analyzing breath for medical diagnosis. We report a highly …

ZnO flowers with different Ag contents were successfully synthesized by a simple microwave
method. Phase and morphologies of heterostructure Ag/ZnO composites were characterized …

PtO2 nanocatalysts-loaded SnO2 multichannel nanofibers (PtO2-SnO2 MCNFs) were
synthesized by single-spinneret electrospinning combined with apoferritin and two …

Nanostructured semiconducting metal oxides (SMOs) hold the potential for playing a critical
role in gas-sensing applications due to their interconnected nanograins, large surface area …

Oxide chemiresistors have mostly been used to detect reactive gases such as ethanol,
acetone, formaldehyde, nitric dioxide, and carbon monoxide. However, the selective and …
