“…Conventional boronate affinity materials require a basic pH (usually ≥pH 8.0) for binding and thereby need a pH adjustment step for these samples, leading to not only inconvenience in operation but also the risk of degradation of labile components. To reduce the binding pH, single boronic acids8b,c or molecular teams8a,d,e with special structures are indispensible. However, the MIP arrays synthesized with a common boronic acid worked well within a pH range of 5.0 to 9.0, which almost covers the pH range of blood, saliva, tears, and urine.…”

“…[19][20][21][22][23] Nanomaterials, such as graphene, carbon nanotubes, and metal-oxidation nanoparticles, [24][25][26] have been modified on electrode surface to 40 enhance the sensitivity of the sensors. [29][30][31][32] PBA can form a negatively charged species characterized by an electron-rich sp3 boron atom with tetrahedral geometry in basic media, which in most cases shows higher binding affinity to cis-diol-containing molecule to form a boronate ester. At the same time, selectivity is also an important property of these sensors due to the high over potentials of phenol 45 compounds without a separation between their oxidation peaks and the coexistence of a variety of organic compounds.…”

A facile electrochemical sensor for hydroquinone (HQ) and catechol (CC) determination was successfully fabricated by the modification of poly(3-aminophenylboronic acid) (pAPBA) film and multi-walled carbon nanotubes (MWCNTs) on a glassy carbon electrode (pAPBA/MWCNTs/GCE). The prepared sensor was characterized by scanning electron microscope and electrochemical impedance spectroscopy. Under optimal conditions, differential pulse voltammetry was employed to quantify individual HQ and CC within the concentration range of 5.0 × 10(-7)-4.0 × 10(-5) mol L(-1) and 7.0 × 10(-6)-1.0 × 10(-4) mol L(-1), respectively. Based on the covalent binding between the boronic acid groups of pAPBA film and the cis-diol-containing molecule, a novel substitution-sensing strategy was proposed for the highly sensitive determination of CC. With the addition of CC into HQ solution, covalent interaction between CC and APBA occurred and the HQ was displaced by CC, resulting in a decrease of HQ oxidation peak current and the increase of the CC oxidation peak current. The summation of both current changes (Δ|IHQ| + Δ|ICC|) were combined for CC sensitive detection in a concentration range of 4.0 × 10(-8)-1.7 × 10(-5) mol L(-1) with a limit of detection of 4.3 × 10(-9) mol L(-1). The sensor was successfully applied to the determination of CC in spiked water samples.

“…There were still some amino residues on the surface of the modified particles that will provide -B-N-'teamed affinity' to extend the application in a lower pH environment. 27,28 Overall, we could therefore draw the conclusion that DFFPBA-agarose gel particles were successfully synthesized.…”

BACKGROUND Tropomyosin is now receiving increasing attention because of its significant allergenic activity in various fishery products but its simple and effective isolation still remains a challenging task. RESULTS An agarose‐based boronate affinity chromatography was produced for the first time to isolate tropomyosin in various fishery products using 3,5‐difluoro‐4‐formyl‐phenylboronic acid as the functional monomer, tris(2‐aminoethyl)amine as the multi‐branched ligand, and agarose gel particles as supporting materials. The agarose concentration, binding pH, and the concentration of elution buffers demonstrated significant effects on separation performance. Under optimized conditions, the purity of the isolated tropomyosin was higher than 90%, with the column adsorption capacity over 1.85 mg mL−1 and the enrichment efficiency over 65%. Such efficiency was also validated with different fish samples including Paralichthys olivaceus, Thunnusthynnus, Oreochromis spp., and Lophius litulon. CONCLUSION In comparison with conventional methods, the established affinity chromatography demonstrated excellent biocompatibility (without involving any organic solvent), better speed (from at least 1–2 days to 3–4 h), and simplicity (from at least five steps to three steps). This suggests that it is a novel and promising technique for the isolation of tropomyosin and other glycoproteins (including most allergens) in foodstuffs. © 2019 Society of Chemical Industry
