“…In this study, several parameters of the developed method with the NiTiONCs@NiTi fiber were compared with those of some reported methods [23–33]. As shown in Supporting Information Table S2, the overall enrichment capability of the developed SPME–HPLC–UV method with the NiTiONCs@NiTi fiber is greater than that of some reported methods [24–26] or even comparable to that of the reported in‐tube SPME–HPLC–DAD method [28,32] and SPME–GC–FID method [28,32].…”

A novel worm‐like nickel‐titanium oxide nanocomposite coating was directly grown on a nickel‐titanium alloy wire by low‐voltage electrochemical anodization in alkaline ethylene glycol and water solution. The in situ growth of nickel‐titanium oxide nanocomposites greatly depended on the volume ratio of ethylene glycol to water and temperature. Coupled to high‐performance liquid chromatography with UV detection by static desorption in the mobile phase, the adsorption performance of the as‐prepared fiber was evaluated for solid‐phase microextraction of representative environmental analytes in water. The results indicate that the as‐prepared fiber exhibits higher extraction capability for polycyclic aromatic hydrocarbons than commercial polydimethylsiloxane and polyacrylate fibers. After optimizing the extraction parameters, the calibration graphs of the developed method was linear in the range of 0.05–200 μg/L with correlation coefficients above 0.998. Limit of detection ranged from 0.013 to 0.145 μg/L for seven target analytes. Relative standard deviations of intraday and interday analyses varied from 4.0 to 5.3% and from 4.7 to 6.3% with the single fiber, respectively. The relative recoveries of 84.4–109% were achieved for highly efficient enrichment and determination of target analytes in spiked river and snow water. Moreover, the as‐prepared fiber can be used more than 200 times.

“…Black Pd coating was prepared on SSWs by reducing the Pd(II) cations in the aqueous solution with the SSW substrate [169]. The satisfactory EEs of the noble metal coatings to phthalate esters and polycyclic aromatic hydrocarbons might be owing to the hydrophobic interactions and the electron-transfer effect between the π-donor system and the empty valency shells of the noble metals [23,[167][168][169].…”

The basic principles for the preparation of SPME fibers with satisfying selectivity, sensitivity, loading capacities and stabilities are summarized here in terms of the physicochemical properties of the coating materials and the supporting substrates of SPME fibers. While the main part of this chapter focuses on the advances in developing the most widely used coating materials, including ionic liquids, polymeric ionic liquids, carbonaceous materials, molecularly imprinted polymers, metal-organic frameworks, metals and metal oxides, conductive polymers, modified silica, as well as their composites, into SPME fibers. Meanwhile, the applications of novel SPME fibers in analyzing diverse analytes in different sample matrices are briefly reviewed, including the emerging applications of SPME in the extraction of bioactive compounds in living animals and plants.Keywords SPME fiber coating Á Ionic liquid Á Polymeric ionic liquid Á Graphene Á Carbon nanotube Á Molecularly imprinted polymer Á Metal-organic framework Á Metal and metal oxide Á Conductive polymer Á Modified silica IntroductionThe outstanding features of solid-phase microextraction (SPME), including rapid and simple operating procedures, slight disturbance to investigated systems, reduced consumption of solvents, and feasibility of automation, continuously inspire new explorations of SPME in various frontiers, such as metabolome detection [1], central nervous systems studies [2], pharmacokinetic studies [3], environmental analysis [4], and food analysis [5].

Further improvements of the method by the same group have implied the preparation of cedar‐like AuNPs as SPME coatings , which were tested in the determination of phthalate esters and aromatic hydrocarbons using HPLC.

The use of solid-phase microextraction coatings based on gold nanoparticles was investigated, focusing the attention on the preparation of nanoparticles with nonclassical reduction agents of HAuCl such as gallic acid and H O , rather than the conventional sodium citrate. All nanoparticles were characterized by diode array spectroscopy, whereas novel nanoparticles prepared with gallic acid and H O were also characterized by microscopic techniques. Solid-phase microextraction coatings were prepared with a layer-by-layer approach. Gallic acid permitted the preparation of stable nanoparticles with milder experimental conditions (1 min, room temperature) and provided the most uniform coatings (thickness ∼3 μm). Seven organochlorine pesticides were determined in different environmental waters using gas chromatography with electron capture detection. Despite the low thickness of the coatings, limits of detection of the entire method down to 0.13 μg/L were obtained. A comparison with the commercial polyacrylate in terms of the partition coefficients of the analytes to the coatings gave logarithm of the partition coefficient values two times higher with gallic acid than polyacrylate (although the commercial fiber is 28 times thicker). Interfiber relative standard deviation values ranged from 8.67 to 21.3%. Optimum fibers also presented an adequate lifetime (>100 extractions).
