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

Abstract

A conceptual sensor array for the efficient discrimination and fast detection of saturated alkanes and commonly found volatile solvents is reported.

Naphthyl End‐Capped Terthiophene‐Based Chemiresistive Sensors for Biogenic Amine Detection and Meat Spoilage Monitoring

“…This testing platform is an improvement of the testing platform used in previously reported studies. [17][18][19][20][21] As an example gas, TMA, was injected (C = 2.11 10 5 ppm, 3s at ar ate of 1.83 mL s À1 )a nd there was ac oncomitant rise in the resistance of the NA-3T-NA sensor.P ump degassing could recover the signal to al evel of 95 %w ithin 23 s. Moreover,t he excellent reusabilityo ft he NA-3T-NA-based sensor was proved by the results from more than 50 cycles of continuous testsw ith TMA (2.11 10 5 ppm) because there had been no observable attenuation in either reversibility or signal intensity (Figure 6c).…”

“…[5,6] About 600 millionp eople get sick every single year, and more than 400 000 peopled ie from unhygienicf oods. [7] Therefore, various techniques, such as quartz crystal microbalance; [8,9] localized surfacep lasmon resonance; [10] radiofrequency identification; [11,12] Raman spectroscopy; [13] and electrochemical, [14,15] fluorescent, [16][17][18][19][20][21][22] and colorimetric sensors, [23,24] have been developed and used for detecting BAs to monitorf ood spoilage. Unfortunately,m ost of these methodsn ot only demands ophisticated instrumentation, but also requiret edious sample preparation and are hard to use on-site.…”

Electrospun fluorescent nanofibrous membranes for trace explosive detection

“…荧光薄膜的检测性能与其制备方法 密切相关. 目前, 荧光薄膜的制备方法主要有涂覆 法 [33] 、旋涂法 [34,35] 、Langmuir-Blogeet膜(LB膜)技 术 [36] 、自组装成膜法 [37] 、静电纺丝法 [38,39] . 其中, 静电 纺丝法因具有方法可控、操作简单、可批量生产等优 点, 被公认为荧光薄膜的高效制备方法.…”

Porous Particle‐Based Inkjet Printing of Flexible Fluorescent Films: Enhanced Sensing Performance and Advanced Encryption

“…Lots of attention has been paid to sensor development, and tremendous progress has been achieved. [9,10] Sensing performance of a film is dependent on both fluorescent sensing unit and substrate, as not only chemical constitution but also microstructure of the adlayer is important www.advmattechnol.de porous particles can be used as environment-friendly ink when ethanol and glycerol were chosen as dispersing solvents. [6][7][8] Fluorescent film is the key part of a reusable fluorescent sensor.…”
