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].

“…Stainless-steel wire has been widely applied to obtain SPME fibers by electropolymerization of conductive polymers or by physical adhesion of the sorbent. Recently, the use of covalently bonded sorbent on stainless steel for fabrication of unbreakable SPME fibers has been reported [13,14]. In this work for fabricating an unbreakable SPME fiber, a self-assembled monolayer (SAM) of 3-(trimethoxysilyl)-1-propanthiol (3-TMSPT) was grafted on an Au wire and then a stationary phase by electrodeposition of 3-(methoxysilyl)propylmethacrylate (3-TMSPMA) as a precursor, tetramethyl orthosilicate (TMOS) and polyethylene glycol (PEG) as a coating polymer was produced.…”

A new technique for preparation of an unbreakable solid-phase microextraction (SPME) fiber, using sol-gel technology is developed. Primarily, an ultrathin two-dimensional intermediate film was prepared by hydrolysis of 3-(trimethoxysilyl)-1-propanthiol self-assembled monolayer grafted onto gold, then a stationary phase by electrodeposition of 3-(trimethoxysilyl)propylmethacrylate as a precursor, tetramethyl orthosilicate and polyethylene glycol as a coating polymer was produced. The scanning electron microscopy images revealed that the new fiber exhibits a rather porous and homogenous surface. The thermal stability of the fabricated fiber was investigated by thermogravimetric analysis. The applicability of the prepared fiber coating in conjunction with gas chromatography-mass spectrometry was examined by SPME of polycyclic aromatic hydrocarbons, as model analytes, from aquatic media. An extraction time of 20 min at 50 °C gave maximum peak areas when NaCl, 15% was added to the aqueous samples. Limits of detection were in the range of 0.01-0.02 ng/mL and relative standard deviation values were in the range of 4-16% at 1 ng/mL. The developed method was successfully applied for the analysis of real water samples while the relative recovery percentage was in the range of 102-118%.

“…In the past years, various SPME coating approaches such as electrochemical procedures [8,9], immobilized resin [10,11], sol-gel technology [12,13] and molecular imprinted technology [6,14] have been developed. For new coating materials, high-porosity materials have attracted much attention recently because of their large specific surface areas and high extraction capacities resulting in significant improvement in sensitivity, such as carbon nanotubes [15], graphene [16,17] and metal-organic framework [7].…”

“…Mesoporous materials are considered the high-efficiency sorbents due to high specific surface area, controllable pore size, narrow pore size distribution, thermal and mechanical stability, which have various applications in chemical industry [18,19], environment [10,[18][19][20], medicine [21,22], adsorption and separation [23]. Compared with conventional mesoporous materials, mesoporous cellular foams (MCFs) have aerogel like, three-dimensional, continuous and ultralarge-pore structure through incorporation of swelling agent [9]. Moreover, MCFs exhibit much higher catalytic activity due to their fast mass transfer kinetics, good accessibility for large molecules (e.g.…”

h i g h l i g h t sTwo novel mesoporous cellular foams were synthesized and used as SPME coating. Four SPME fibers were prepared by sol-gel technology and immobilized resin method. New coating had excellent extraction ability to seven brominated flame retardants. g r a p h i c a l a b s t r a c t a r t i c l e i n f o a b s t r a c tTwo kinds of mesoporous cellular foams (MCFs), including mesoporous silica materials (MCF-1) and phenyl modified mesoporous materials (Ph-MCF-1), were synthesized and for the first time used as fibercoating materials for solid-phase microextraction (SPME). By using stainless steel wire as the supporting core, four types of fibers were prepared by sol-gel method and immobilized by epoxy-resin method. To evaluate the performance of the home-made fibers for SPME, seven brominated flame retardants (BFRs), including tetrabromobisphenol A (TBBPA), tetrabromobisphenol S (TBBPS) and related compounds were selected as analytes. The main parameters that affect the extraction and desorption efficiencies, such as extraction temperature, extraction time, desorption time, stirring rate and ionic strength of samples were investigated and optimized. The optimized SPME coupled with high performance liquid chromatography (HPLC) was successfully applied to the determination of the seven BFRs in water samples. The linearity range was from 5.0 to 1000 g L −1 for each compound except TBBPS (from 1.0 to 1000 g L −1 ), with the correlation coefficients (r 2 ) ranging from 0.9993 to 0.9999. The limits of detection of the method were 0.4-0.9 g L −1 . The relative standard deviations varied from 1.2 to 5.1% (n = 5). The repeatability of fiber-to-fiber and batch-to-batch was 2.5-6.5% and 3.2-6.7%. The recoveries of the BFRs from aqueous samples were in the range between 86.5 and 103.6%. Compared with three commercial fibers (100 m PDMS, 85 m PA and 65 m PDMS/DVB), the MCFs-coated fiber showed about 3.5-fold higher extraction efficiency.
