“…In order to obtain the most sensitive modified sensor towards the vapors of aromatic hydrocarbons, Banerjee et al [ 79 ] modified the surface of a silver-coated QCM with different polymers. Different polymerization mixtures including various template molecules were evaluated.…”

“…It was found that the larger amount of MIP coating hardly couples mechanically to the QCM and the quartz crystal may permanently damage due to disproportionate mass deposition on the quartz wafer. Also, the thicker coatings of MIP on the QCM surface flake off easily, resulting in a reduced sensitivity of the sensor [ 79 ]. Analyzing the gaseous samples with MIP-modified sensors needs generally a prolonged sampling time.…”

“…The functionality of the used sensors is mainly based on the optical (fluorescence [ 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 ], phosphorescence [ 45 , 46 , 47 , 48 ], chemiluminescence [ 49 ] or color-change [ 50 , 51 ]) and electrochemical (electrochemical impedance spectroscopy [ 52 ], potentiometric [ 53 , 54 ] or voltammetric methods [ 55 , 56 , 57 , 58 , 59 , 60 , 61 , 62 , 63 , 64 , 65 , 66 , 67 , 68 , 69 , 70 , 71 , 72 , 73 , 74 ]) detection techniques.

“…Additionally, in gaseous samples, mass-transfer of the template molecules between the sample matrix and the imprinted recognition sites within the highly cross-linked polymer network is low and resulted, mostly, to a prolonged sampling time. There are some reports in which MIP-modified sensors were used for detection of benzene (boiling point: 80.81 °C; vapor pressure: 94.8 mm Hg at 25 °C) [ 78 , 79 , 81 ], toluene (boiling point: 111 °C; vapor pressure: 28.4 mm Hg at 25 °C) [ 54 , 77 , 79 , 81 , 84 ], xylenes (boiling points for ortho -: 144 °C, meta -: 139 °C and para -: 138 °C; vapor pressures at 20°C for ortho -: 7 mmHg, meta -: 9 mmHg and para -: 9 mmHg) [ 77 , 79 , 81 ], nitrobenzene (boiling point: 211 °C; vapor pressure 0.245 mm Hg at 25 °C) [ 83 ] and 2,4-dinitrotoluene (boiling point: decomposes at 250–300 °C; vapor pressure: 1.47 × 10 −4 mm Hg at 22 °C) [ 44 ] in the gaseous samples. These chemicals belong to either the group of very volatile organic compounds (VVOCs) or volatile organic compounds (VOCs), which can be present with higher concentrations in air.…”

Globally, there is growing concern about the health risks of water and air pollution. The U.S. Environmental Protection Agency (EPA) has developed a list of priority pollutants containing 129 different chemical compounds. All of these chemicals are of significant interest due to their serious health and safety issues. Permanent exposure to some concentrations of these chemicals can cause severe and irrecoverable health effects, which can be easily prevented by their early identification. Molecularly imprinted polymers (MIPs) offer great potential for selective adsorption of chemicals from water and air samples. These selective artificial bio(mimetic) receptors are promising candidates for modification of sensors, especially disposable sensors, due to their low-cost, long-term stability, ease of engineering, simplicity of production and their applicability for a wide range of targets. Herein, innovative strategies used to develop MIP-based sensors for EPA priority pollutants will be reviewed.

Lung cancer is the leading cause of death worldwide and has a significant impact on public health across society. Among all types of cancer, lung cancer is typically silent and it is commonly diagnosed at a later stage where treatment is rarely achievable. There is an urgent need for the development of the early diagnosis of lung cancer for an improved survival rate. Preliminary research shows that lung cancer is accompanied by increased oxidative stress which generates volatile organic compounds (VOCs). Hence, breath analysis offers the most promising solution for the early diagnosis of lung cancer as it is noninvasive and radiation free. Potential VOCs biomarkers in exhaled breath associated with oxidative stress and lipid peroxidation have been discussed to provide a quick approach to the diagnosis of lung cancer. Although gas chromatography-mass spectroscopy (GC-MS) able to analyze the VOCs biomarker, it is bulky, high cost, required expertise to handle and consumes a lot of time. Hence, the sensor-based technique provides the solution to overcome the limitation. Recently, acoustic wave sensors such as quartz crystal microbalance (QCM) and surface acoustic wave sensors (SAW) have been used to identify the presence of VOCs in various applications. This is due to its high selectivity, good reproducibility, and fast response sensing materials. The selection of vapour sensing materials plays a crucial role in developing a highly sensitive and selective and fast response acoustic wave sensors. For this purpose, various types of sensing layers from metal oxides, polymers, biopolymers and composites have been studied. We present a critical review of advanced vapour sensing materials that are primarily used in acoustic wave sensors in identifying the presence of various VOCs. Criteria to evaluate the performance of the acoustic wave sensors such as resonance frequency and sensitivity are also discussed.
