Tailoring selectivity of sprayed carbon nanotube sensors (CNT) towards volatile organic compounds (VOC) with surfactants

Discrimination of saturated alkanes and relevant volatile compounds via the utilization of a conceptual fluorescent sensor array based on organoboron-containing polymers

“… 39 In particular, some short-chain saturated alkanes, such as n -pentane, n -heptane and n -decane, are frequently found in expired air from patients with lung cancer, asthma, and other respiratory diseases. 3b , 40 Inspection of the data shown in Table 1 reveals that the solvation of the polymers could result in enhanced fluorescence emission as their emissions in the solution state are always stronger than those in the film state. Moreover, the silica-gel plate possesses a greater absorption capability towards solvent molecules than that of routine glass plates.…”

Carbon Nanotube Based Gas Sensors toward Breath Analysis

“…Chatterjee et al. replaced DNA with a series of different surfactants to create a chemiresistor array of surfactant‐functionalized MWCNTs . Although no single VOC could be sensed by a surfactant‐functionalized MWCNT chemiresistor, an array of these sensors was able to differentiate toluene, chloroform, acetone, ethanol, methanol, and water by using PCA.…”

Carbon nanotube-alumina strips as robust, rapid, reversible adsorbents of organics

“…with a hydrophobic surface property, high chemical stability and exohedral surface, were recently intensively studied for uses as a promising adsorbent for the separation of organics from water, [1][2][3][4][5][6][7][8][9][10] or for the trapping of trace organics in air, [11][12][13] which are all challenging issues in environmental protection. Most of the previous work has focused on conceptual separation, and this has probably been because of the limited availability of samples of CNTs.…”
