This current review focuses on contributions to exhaled breath (EB) preparation in drug of
abuse (DOA) detection. DOA has caused health hazards, accidents, criminal acts and huge …

Artificial Intelligence (AI) has the potential to dramatically change the field of healthcare and
nutrition by imitating human cognitive processes. This field involves smart machine-based …

An optimized acetone gas sensor based on Ti3C2/α-Fe2O3 (TF) composite materials was
synthesized using microwave and etching methods. The structures, morphology and …

The detection of acetone is of great significance for environmental safety and human health.
Micromorphology control is a feasible pathway to obtaining excellent gas-sensitive …

Gas sensors play an important role in environmental detection and exhaled breath
biomarker detection. In this paper, Co 3 O 4/TiO 2 core-shell NFs were synthesized by …

The development of a suitable chemical route for the synthesis of exotic nanoarchitectures
as a promising candidate for reliable volatile organic compounds (VOCs) monitoring …

In recent years, clinical studies have found that acetone concentration in exhaled breath can
be taken as a characteristic marker of diabetes. Metal–oxide–semiconductor (MOS) …

In this work, a group-11 metal nanoparticle-embedded, graphitic carbon nitride-based,
resistive-type sensor was developed for room temperature acetone sensing. We synthesized …

Acetone is a biomarker of diabetics. The exhaled acetone concentration of diabetics is
higher than that of a healthy person. Semiconductor gas sensors provide an accurate non …

In this paper, the UV illumination effect for microwave gas sensors based on the tin dioxide
was verified. A UV LED with emission wavelength close to the absorption edge of the SnO2 …
