In recent years, many novel sensing nanomaterials were explored experimentally and
theoretically as chemical gas sensors to detect sulphur hexafluoride (SF6) decomposed …

The detection of cancer at an early stage is often significant in the successful treatment of the
disease. Tumor cells have been reported to generate unique cancer volatile organic …

This work aims at a broad overview of the results obtained with metal-sulfide materials in the
field of chemoresistive gas sensing. Indeed, despite the well-known electrical, optical …

Improvements in the responses of semiconductor gas sensors and reductions in their
detection limits toward volatile organic compounds (VOCs) are required in order to facilitate …

Upon contact with bodily fluids, synthetic materials spontaneously acquire a layer of various
species (most notably proteins) on their surface. The concern with respect to biomedical …

Reproducibility of the sensor response is one of the fundamental themes for obtaining
marketable devices with a high degree of reliability. This parameter becomes decisive …

This paper reports a facile functionalization method on a metal-oxide semiconductor and a
cuprous oxide (Cu2O) based chemiresistive electronic nose for the detection of volatile …

The impact of diet and digestive disorders in flatus composition remains largely unexplored.
This is partially due to the lack of standardized sampling collection methods, and the easy …

Background Cancer is a significant public health problem, causing dozens of millions of
deaths annually. New cancer screening programs are urgently needed for early cancer …
