“…In addition, the steric hindrance within the monomeric units, i.e., the tacticity, could influence the degradation process [ 9 ]. Therefore, the evaluation of the changes in the PVC properties under service conditions is very important in order to find ways to improve the durability of PVC containing products [ 12 , 13 ]. The susceptibility of PVC polymeric materials to UV light (300–400 nm) has been investigated [ 14 , 15 , 16 ].…”

Three organotin(IV) complexes containing ciprofloxacin as a ligand (Ph3SnL, Me2SnL2 and Bu2SnL2; 0.5% by weight) were used as additives to inhibit the photodegradation of polyvinyl chloride films (40 µm thickness) upon irradiation with ultraviolet light (λmax = 313 at a light intensity = 7.75 × 10−7 ein dm−3 S−1) at room temperature. The efficiency of organotin(IV) complexes as photostabilizers was determined by monitoring the changes in the weight, growth of specific functional groups (hydroxyl, carbonyl and carbene), viscosity, average molecular weight, chain scission and degree of deterioration of the polymeric films upon irradiation. The results obtained indicated that organotin(IV) complexes stabilized poly(vinyl chloride) and the dimethyltin(IV) complex was the most efficient additive. The surface morphologies of poly(vinyl chloride) films containing organotin(IV) complexes were examined using an atomic force microscope and scanning electron microscopy. These showed that the surface of polymeric films containing organotin(IV) complexes were smoother and less rough, compared to the surface of the blank films. Some mechanisms that explained the role of organotin(IV) complexes in poly(vinyl chloride) photostabilization process were proposed.

“…Poisons including cyanide, arsenic, nightshade, hemlock, curare, nicotine, caffeine, quinine, atropine, strychnine, and brucine were also intensively evaluated targets in the MIP literature [ 31 , 32 , 33 , 34 ]. Jackson et al imprinted 2-aminothiazoline-4-carboxylic acid (ATCA), a chemically stable metabolite of cyanide, on the surface of a silica stir bar and used it for determining the endogenous level of ATCA in cases of cyanide poisoning.…”

“…They inserted a hydrophobic chains (dodecanol) on the nanoparticles to improve durability, lifetime, and analytical characteristic of the polymeric membrane electrodes. They used the sensor for arsenic determination in different water samples and reported a wide concentration range of 5.0 × 10 −8 –1.0 × 10 −1 M with a LOD value as 30 nM [ 33 ]. Nakamura et al followed precipitation polymerization and multistep swelling and polymerization techniques to form monodisperse MIPs for strychnine recognition.…”

Producing molecular imprinting-based materials has received increasing attention due to recognition selectivity, stability, cast effectiveness, and ease of production in various forms for a wide range of applications. The molecular imprinting technique has a variety of applications in the areas of the food industry, environmental monitoring, and medicine for diverse purposes like sample pretreatment, sensing, and separation/purification. A versatile usage, stability and recognition capabilities also make them perfect candidates for use in forensic sciences. Forensic science is a demanding area and there is a growing interest in molecularly imprinted polymers (MIPs) in this field. In this review, recent molecular imprinting applications in the related areas of forensic sciences are discussed while considering the literature of last two decades. Not only direct forensic applications but also studies of possible forensic value were taken into account like illicit drugs, banned sport drugs, effective toxins and chemical warfare agents in a review of over 100 articles. The literature was classified according to targets, material shapes, production strategies, detection method, and instrumentation. We aimed to summarize the current applications of MIPs in forensic science and put forth a projection of their potential uses as promising alternatives for benchmark competitors.

“…In addition to the organic molecules, important metal ions are also included in the EPA Priority Pollutant List. In order to monitor the quality of water samples, different sensors were modified with ion imprinted polymers (IIPs) for sensitive and selective detection of metal ions including arsenic [ 88 , 89 ], mercury [ 90 ], cadmium [ 91 , 92 ], chromium [ 93 , 94 ], copper [ 95 , 96 ], lead [ 97 , 98 ], silver [ 99 ], thallium [ 100 ] and zinc [ 101 ]. However, IIPs and metal ions are not in the scope of this review and are not discussed here.…”

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.
