A novel technique for simultaneous determination of drugs using magnetic nanoparticles based dispersive micro-solid-phase extraction in biological fluids and wastewaters

Pharmacokinetic study and the extraction efficiency of bulk and precipitated ibuprofen‐imprinted polymer sorbents for gas chromatography and gas chromatography‐mass spectrometry ibuprofen bio‐analysis

“…Also, due to the comparative nature of the study -a comparison of the extraction and analytical efficiency of four synthesized MIP samples prepared by two polymerization methods-, establishing a highly sensitive analytical method was not our main aim. Although, some obtained terms are comparable or superior compared to other ibuprofen analysis methods [5][6][38][39][40][41]. Table S4 shows the analytical characteristics of five other studies for ibuprofen analysis in comparison to our study.…”

Benzodiazepines in complex biological matrices: Recent updates on pretreatment and detection methods

“…SPME has been used for sample pretreatments to cater to the shortfalls of SPE, as shown in Table S3 [ 40 , 60 , 102 , [121] , [122] , [123] , [124] , [125] , [126] , [127] , [128] , [129] , [130] , [131] , [132] , [133] , [134] , [135] , [136] , [137] , [138] , [139] , [140] , [141] , [142] ]. The principle of SPME is based on the equilibrium partitioning of substances to be separated between stationary and aqueous phases rather than the extraction of substances measured in their entirety.…”

“…Shiri et al. [ 131 ] prepared magnetic nanoparticles (Fe 3 O 4 @SiO 2 @Kit-6@NH 2 ) for dSPME of clonazepam from biological fluids and wastewaters with the recovery of 94.6%–100.7%. The optimized adsorption time was 6 min.…”

“…Only 25 mg of nanoparticles as adsorbent and 30 μL of methanol as eluting solvent was consumed in dSPME. The application of auxiliary technology such as vortex-assisted dSPME [ 131 ], and ultrasonic-assisted dSPME [ 132 ] make the dispersion of adsorbent more rapid and uniform, thus shortening the sample pretreatment time.…”

Synthesis and characterization of poly(styrene-co-divinylbenzene) and nanomagnetite structures

“…The adsorption process is widely studied for the remediation of wastewater, being a viable alternative for trace concentrations of contaminants. In this sense, the use of nanoparticulate iron oxide in the synthesis of polymeric adsorbents has the advantage of associating magnetic and adsorptive properties [1] , [2] , [3] , [4] . Styrene-divinylbenzene copolymer microparticles (Poly(Sty-co-DVB)) are widely known for this use, and the addition of magnetite to the synthesis process aiming to add magnetic properties must be done without limiting the adsorbent functionalization processes, with the purpose of forming cationic and/or anionic resins [5] .…”
