The scope of the applications of breath sensors is abundant in disease diagnosis. Lung
cancer diagnosis is a well-fitting health-related application of this technology, which is of …

The last three decades have witnessed an increasing demand for novel analytical tools for
the analysis of gases including odorants and volatile organic compounds (VOCs) in various …

In this paper, we review the utilization of surface acoustic waves in biosensing applications.
A brief background on the theoretical aspects and on the modeling principles for acoustic …

Whilst the senses of vision and hearing have been successfully automated and miniaturized
in portable formats (eg smart phone), this is yet to be achieved with the sense of smell. This …

Among all the senses, olfactory system of mammals is the least characterised as far as the
mechanisms of odour identification are concerned. The results of recent investigations allow …

The biological olfactory system can recognize and discriminate thousands of volatile organic
compounds (VOCs) with extremely high sensitivity and specificity. The most fundamental …

Animals can easily detect hundreds of thousands of odors in the environment with high
sensitivity and selectivity. With the progress of biological olfactory research, scientists have …

Biohybrid odorant sensors that directly integrate a biological olfactory system have been
increasingly studied and are suggested to be the next generation of ultrasensitive sensors …

Despite substantial progress during the last decades made in the food analysis field, there is
still need for faster, portable, and more accurate approaches. This chapter presents a …

Inspired by the very high sensitivity and specificity of biological olfactory system, engineers
pay much attention to biomimetic olfactory biosensors due to their excellent performance …
