“…Then, the valence states of the embedded Fe ions were further verified. As the ionic radii of W 6+ , Fe 3+ , and Fe 2+ are 0.0600, 0.0550, and 0.0630 nm, respectively [26,27], the replacement of W 6+ ions in WO 3 with larger metal ions will contribute to the enlargement of a crystal cell [28]. As the synthesized Fe-doped WO 3−x belongs to the monoclinic crystal system, the lattice constants (a, b, and c) can be obtained by Eq.…”

In the assessment of food quality, geranyl acetone plays a crucial role as a volatile organic compound (VOC) biomarker for diverse agricultural products, while the ultralow concentration detection meeting application requirements has been barely studied. Herein, an iron (Fe)-doped WO 3−x gas sensor was employed for greatly sensitive, selective, and scalable geranyl acetone detection. The results proved that precisely-regulated oxygen vacancy (O V ) and sophisticatedly-active electron transition of Fe-doped WO 3−x nanoparticles were fulfilled by modifying the doping amount of Fe 3+ , leading to the prominently enhanced sensitivity (23.47 at 6 ppm), low limit of detection (LOD) (237 ppb), optimal selectivity, and outstanding long-term stability. Furthermore, the enhancing mechanism of gas sensing performance was substantiated through density functional theory (DFT) calculation, while the practical application for the evaluation of spoiled cooked rice was conducted as well. This study demonstrates a reliable method for detecting a VOC biomarker in cooked rice, which can ensure food security and improve palatability of cooked rice.

“…The morphology and the crystalline phase of the materials were varied with respect to the concentration of the W; the olive-shaped nanoparticles were obtained on the surface of the nanowire. The 6% mol W-doped ZnFe 2 O 4 materials achieved the highest response towards the detection of acetone as 0.125 ppm acetone vapor at 200 • C. The W-doping on the surface of the nanowire is five times higher than the un-doping nanowire [52].…”

The present review article discusses the elementary concepts of the sensor mechanism and various types of materials used for sensor applications. The electrospinning method is the most comfortable method to prepare the device-like structure by means of forming from the fiber structure. Though there are various materials available for sensors, the important factor is to incorporate the functional group on the surface of the materials. The post-modification sanction enhances the efficiency of the sensor materials. This article also describes the various types of materials applied to chemical and biosensor applications. The chemical sensor parts include acetone, ethanol, ammonia, and CO2, H2O2, and NO2 molecules; meanwhile, the biosensor takes on glucose, uric acid, and cholesterol molecules. The above materials have to be sensed for a healthier lifestyle for humans and other living organisms. The prescribed review articles give a detailed report on the Electrospun materials for sensor applications.

“…Among various analytical techniques, gas sensors may be the most promising method on account of their low cost, simplicity and convenience. 7,8 Semiconductor metal oxides (SMOs), which are promising gas-sensing materials, have been widely studied for the detection of inflammable, explosive and toxic gases thanks to their high sensitivity, easy preparation and convenient integration. [9][10][11][12][13] Numerous SMOs, such as ZnO, [14][15][16] SnO 2 , [17][18][19][20] In 2 O 3 , [21][22][23] Fe 2 O 3 , [24][25][26] TiO 2 , 27 WO 3 [28][29][30][31] etc., have been extensively used as sensing materials.…”
