“…In order to balance the sensitivity for the analysis using any of the dyes and considering that a small fraction of AAP/DHBS may leach out of from the beads (as previously discussed), an optimum analysis time of 300 sec was selected and used for all further analyses. Previous reports have described the possibility to used alginate beads as a support to trap other materials (typically hydrophobic) that act as adsorbents 7,[17][18][19][80][81][82] and for which controlling the sample volume is essential. Considering this possibility, the color intensity of the ALGPODES beads modified with GOx/HRP-ODI was investigated as a function of the sample volume, in the range between 500 µL and 1500 µL.…”

Natural polymers offer not only low-cost, wide availability, biocompatibility, and biodegradability but also a rich chemical functionality towards custom modifications and new applications. Among those, sodium alginate (ALG) offers a number of competitive advantages, including the possibility to form beads by a simple process call spherification as well as their modification by a wide number of processes, including the possibility to mixing the alginate solution with deep eutectic solvents (DES). Thus, and considering the capacity of DES to stabilize enzymes, the main objective of this work was to design and fabricate a new PODES (using ALG as one of the components, ALGPODES) and to deploy this material as a new phase to develop colorimetric biosensors. The formed beads displayed a narrow size distribution (2.9 0.1 mm) and a permeable structure with large internal cavities (25-100 m). The applicability of these beads towards analytical applications (lab-on-a-bead) was demonstrated by integrating three sensing platforms and by their application in real food samples.

“…Polycyclic aromatic hydrocarbon (PAH) is a complex class of condensed multi-ring benzenoid compounds in linear, angular, or cluster arrangements. Due to their highly carcinogenic and mutagenic properties, PAHs have garnered growing interest in contemporary pollution research [1,2]. Based on their frequency of occurrence in the environment, the United States Environmental Protection Agency (US-EPA) has identified 16 unsubstituted PAHs as priority pollutants [3].…”

In this study, a composite material consisting of three-dimensional graphene aerogel and iron oxide nanoparticles (3DG/Fe3O4) was created and utilized for the purpose of magnetic solid-phase extraction (MSPE) of thirteen polycyclic aromatic hydrocarbon (PAH) compounds via gas chromatography–mass spectrometry/selected ion monitoring (GC-MS/SIM) analysis. The synthesized adsorbent underwent a range of characterization techniques, including scanning electron microscopy, vibrating sample magnetometry, Raman spectroscopy, X-ray diffraction, Brunauer–Emmett–Teller, Fourier transform-infrared spectroscopy, and Barrett–Joyner–Halenda techniques, to examine its properties and morphology. The synthesized adsorbent integrates the benefits of superior adsorption capacity from modified graphene oxide (GO) with the magnetic separability of magnetite microparticles, resulting in a high adsorption capacity with easy separation from sample solutions. The efficiency of the proposed method was optimized and modeled using a central composite design (CCD), which considered the primary factors influencing it. The optimal conditions were obtained as the adsorbent dosage of 10 mg, the extraction time of 4 min, and the salt concentration of 3% w/v. The limit of detection for the target PAHs was established to range from 0.016 to 0.2 ng mL−1 in optimal conditions, exhibiting a signal-to-noise ratio of 3. The linear dynamic range spanned from 5 to 100 ng mL−1, with determination coefficients (R2) ranging from 0.9913 to 0.9997. The intra- and inter-day precisions were calculated as relative standard deviations (RSDs) equal to 3.9% and 4.7%, respectively. The proposed method was successfully applied to the determination of PAHs in water samples (tap, river, and rainwater), and recoveries in the range of 71–110% (RSDs < 5.2%, n = 3) were obtained.
