Preparation of teamed boronate affinity magnetic nanoparticles for extraction of polyphenols from Flos Lonicerae Beverage under neutral pH prior to their determination by high-performance liquid chromatography-mass spectrometry

Recent trends in sorbents for bioaffinity chromatography

“…In the first strategy, PBA functionalized monomers such as 3-aminophenylboronic acid (APBA) [95][96][97], 4-vinylphenylboronic acid (VPBA) [94,98,99], and vinylboronic anhydride pyridine complex [100] are used in the synthesis of polymer-based boronate affinity sorbents in the form of microspheres and monoliths. PBA functionalized thermosensitive latex particles prepared by dispersion copolymerization of isopropylacrylamide (NIPA) and VPBA were evaluated for temperature-controlled isolation of RNA via BAC [101].…”

“…Teamed boronate affinity magnetic nanoparticles were synthesized by Fan et al. [96]. Prior to boronate affinity functionalization, magnetic nanoparticles were reacted with 3‐aminopropyltrimethoxysilane to form amine groups on the surface of magnetic nanoparticles.…”

“…Prior to boronate affinity functionalization, magnetic nanoparticles were reacted with 3‐aminopropyltrimethoxysilane to form amine groups on the surface of magnetic nanoparticles. Then, tri(2,3‐epoxypropyl)isocyanurate, APBA, and hexamethylenediamine (HMDA) were covalently attached onto the amine‐functionalized magnetic nanoparticles by initiator‐free ring‐opening polymerization [96]. A boronate affinity stationary phase for enrichment of cis ‐diol compounds via mixed‐mode chromatography was synthesized by the copolymerization of NIPA and APBA on silica microspheres through atom transfer radical polymerization [97].…”

Preparation of P(EGDMA‐co‐VPBA) Adsorbent and Its Application in the Separation of Steviol Glycosides

“…[6] In recent years, with the development of adsorption materials, the adsorption method has been regarded as a high efficiency separation method. [7] The adsorption materials commonly used in current research involve MOFs, [8] silica-based materials, [9,10] carbon-based materials, [11,12] magnetic composite [13][14][15] and macroporous adsorption resin (MAR), COFs, [16,17] molecularly imprinted polymers (MIPs), [18][19][20][21][22][23][24] and other organic polymers. [25][26][27][28][29] Organic polymer adsorbents have become universal adsorbent materials with varieties of attractive merits, for example adjustable monomer components, relatively low-cost, structure diversity, and facile functionalization.…”

Highly Efficient Photodegradation of RHB-MO-MB Mixture Dye Wastewater by WO3/Fe3O4/Diatomite under Different Condition

“…Diatomaceous Earth was compounded based on the optimal composite ratio of WO 3 and Fe 3 O 4 . On the one hand, the material has more surface hydroxyl groups, and on the other hand, the larger specific surface area of diatomaceous Earth will reduce the agglomeration of Fe 22 First, an amount of FeCl 3 •6H 2 O and (CH 2 OH) 2 were stirred. And then 8.2 g C 2 H 3 NaO 2 was added to the above solution and stirred for 0.5 h. The solution then was moved to the reaction kettle heated to 200 °C for 8 h. Characterization of photocatalysts.-The composition and crystal structure of the samples were analyzed by X-ray diffraction (XRD, Brukerd 8, λ = 1.54184 Å, 40 kV, 40 mA), and the test angle is 10-80•.…”
