Benzene is ah ighly toxic aromatic hydrocarbon. Inhalingb enzene can cause dizziness,v ertigo, headaches, aplasia,m utations and, in the moste xtreme cases, cancer. Trans,trans-muconic acid (t,t-MA) is one of the metabolization products of benzene. Although different analytical methods have been reported for the determination of t,t-MA, these are often expensive, requiret rainedp ersonnel, are not suitable foro n-site measurements, and use hazardous organics olvents. For theser easons, the development of reliable, selective and sensitivem ethodsf or rapid and in situ detection of t,t-MA are of importance. Addressing this challenge, an anodevice for the selectivea nd sensitive quantification of t,t-MA in urine is reported. The nanodevice used is achieved using mesoporous silica nanoparticles loaded with ad ye reporter and capped with ad icopper(II) azacryptand. Pore openinga nd payload release is induced rapidly (10min) and selectively with t,t-MA in urine, using as imple fluorimeter without sample pretreatment.

Polycyclic aromatic hydrocarbons (PAHs) comprise a group of chemical compounds consisting of two or more fused benzene rings. PAHs exhibit hydrophobicity and low water solubility, while some of their members are toxic substances resistant to degradation. Due to their low levels in environmental matrices, a preconcentration step is usually required for their determination. Nowadays, there is a wide variety of sample preparation techniques, including micro-extraction techniques (e.g., solid-phase microextraction and liquid phase microextraction) and miniaturized extraction techniques (e.g., dispersive solid-phase extraction, magnetic solid-phase extraction, stir bar sorptive extraction, fabric phase sorptive extraction etc.). Compared to the conventional sample preparation techniques, these novel techniques show some benefits, including reduced organic solvent consumption, while they are time and cost efficient. A plethora of adsorbents, such as metal-organic frameworks, carbon-based materials and molecularly imprinted polymers, have been successfully coupled with a wide variety of extraction techniques. This review focuses on the recent advances in the extraction techniques of PAHs from environmental matrices, utilizing novel sample preparation approaches and adsorbents.

“…As these properties are valued for materials used in separation techniques, it is only natural for different carbon allotropes to attract considerable attention as potential SPE sorbents. In fact, as mentioned earlier, graphitized carbon black is one of the sorbents currently utilized and distributed with the QuEChERS standard procedure kits as a sorbent for the dSPE clean-up step [ 6 , 35 , 36 , 37 ].…”

Solid phase extraction (SPE) is an analytical procedure developed with the purpose of separating a target analyte from a complex sample matrix prior to quantitative or qualitative determination. The purpose of such treatment is twofold: elimination of matrix constituents that could interfere with the detection process or even damage analytical equipment as well as enriching the analyte in the sample so that it is readily available for detection. Dispersive solid phase extraction (dSPE) is a recent development of the standard SPE technique that is attracting growing attention due to its remarkable simplicity, short extraction time and low requirement for solvent expenditure, accompanied by high effectiveness and wide applicability. This review aims to thoroughly survey recently conducted analytical studies focusing on methods utilizing novel, interesting nanomaterials as dSPE sorbents, as well as known materials that have been only recently successfully applied in dSPE techniques, and evaluate their performance and suitability based on comparison with previously reported analytical procedures.
