“…PDAs are known to display a distinctive color change in response to not only a thermal stress but also to other stimuli such as mechanical pressure, [ 27 ] organic solvent, [ 28 ] and pH of medium. [ 29 ] If these chromic transition responses to environmental perturbations also occur with PDAs printed on paper, the technique could be utilized in the form of fl exible and disposable litmus-type sensor system.…”

Inkjet-printable aqueous suspensions of conjugated polymer precursors are developed for fabrication of patterned color images on paper substrates. Printing of a diacetylene (DA)-surfactant composite ink on unmodified paper and photopaper, as well as on a banknote, enables generation of latent images that are transformed to blue-colored polydiacetylene (PDA) structures by UV irradiation. Both irreversible and reversible thermochromism with the PDA printed images are demonstrated and applied to flexible and disposable sensors and to displays.

“…Nanofibrous or NFN membranes which could afford a great number of activity sites for immobilization of sensing materials and reactions have attached tremendous attention. Generally, the nanofibrous or NFN membrane-based colorimetric sensors are prepared by immobilizing the probe which could specifically react with analytes on nanofibrous membranes through various methods, including in situ polymerization, dip coating, or direct electrospinning [33,104]. Due to the outstanding properties of colorimetric sensors, such as cost-effectiveness, portability, easy to use (detected by the color change that could be observed by the naked eye), and semiquantitative determination, many researchers have focused on the development of colorimetric sensors towards various analytes.…”

Monitoring of usable, explosive, and hazardous materials (gases, heavy metal ions, and organic contaminants) is one of the most important concerns that has attracted growing attention in the past few decades. Numerous sensors have been developed to meet the demands and the pursuit of highly sensitive, selective, reversible, fast response and recovery, cost-effective, and portable sensors which have gained great interest. Electrospun nanofibrous membranes that possess large surface area, high porosity, good interconnected porous structure, and flexibility of surface functionalization are expected to be ideal candidates of substrates to improve the performance of the sensors. More interestingly, the novel two-dimensional nanofiber/net membranes fabricated by electrospinning/netting are demonstrated to have extremely large surface area and unique pore structure, which could further enhance the sensitivity, stability, and response speed of the sensors. In this chapter, we summarize recent progress in the development of electrospun nanofiber-based sensors, describe the design of different types of sensors, and discuss their sensing performances in detail. This chapter might bring further development and evolution of sensors based on electrospun nanofibers for the detection of various analytes.

“…The excessive amount of these solvents in gasoline may lead to engine damage, rubber degradation and environmental hazards, as well as tax evasion [1]. Different analytical methods including the spectroscopic and chromatographic techniques combined with chemometric methods have been developed for the study of gasoline adulteration [2,6,11,13,[15][16][17][18][19][20][21]. Among these methods, GC coupled with various detection methods has been widely used to evaluate the quality of gasoline [22][23][24].…”

Comprehensive two-dimensional gas chromatography and flame ionization detection combined with unfolded-partial least squares is proposed as a simple, fast and reliable method to assess the quality of gasoline and to detect its potential adulterants. The data for the calibration set are first baseline corrected using a two-dimensional asymmetric least squares algorithm. The number of significant partial least squares components to build the model is determined using the minimum value of root-mean square error of leave-one out cross validation, which was 4. In this regard, blends of gasoline with kerosene, white spirit and paint thinner as frequently used adulterants are used to make calibration samples. Appropriate statistical parameters of regression coefficient of 0.996-0.998, root-mean square error of prediction of 0.005-0.010 and relative error of prediction of 1.54-3.82% for the calibration set show the reliability of the developed method. In addition, the developed method is externally validated with three samples in validation set (with a relative error of prediction below 10.0%). Finally, to test the applicability of the proposed strategy for the analysis of real samples, five real gasoline samples collected from gas stations are used for this purpose and the gasoline proportions were in range of 70-85%. Also, the relative standard deviations were below 8.5% for different samples in the prediction set.
