“…Figure (inset plot) shows the Langmuir fitting curve; the maximum adsorption capacity of PGMA@FPBA adsorbent was calculated to be 448 μmol/g (Table S2). Compared with other boronate‐affinity adsorbents (Table ), the PGMA@FPBA was prepared with only one step and exhibited a higher binding capacity than the boronate‐affinity materials, except for one boronate‐affinity material . Moreover, the adsorption equilibrium was achieved within 1 min, indicating faster adsorption kinetics than other reported boronate‐affinity materials.…”

“…Boronate‐affinity material is key for the process of boronate‐affinity extraction, and the preparation of high‐capacity boronate‐affinity material is a focus in this field in recent years. To date, boronate‐affinity materials on various supports, such as monolithic column, magnetic nanoparticles, silica gel, and organic polymers, have been reported for the selective capturing of cis ‐diol‐containing biomolecules. However, most of these boronate‐affinity materials have low adsorption capacity.…”

Boronate‐affinity adsorbents have been regarded as favorable extraction adsorbents for the pretreatment of cis‐diol‐containing biomolecules owning to their specific selectivity, but most of them have low adsorption capacity and a tedious synthesis methods. In this study, a new boronate‐affinity material (PGMA@FPBA) with high adsorption capacity was synthesized via a “one‐pot” method based on a low‐cost commercial support. The PGMA@FPBA was characterized by Fourier transform infrared spectroscopy (FT‐IR), X‐ray photoelectron spectroscopy (XPS), scanning electron microscope (SEM), and nitrogen adsorption/desorption measurements. The as‐prepared adsorbent showed good selectivity, high adsorption capacity (448 μmol/g for catechol), and fast adsorption equilibration (1 min) for cis‐diol‐containing biomolecules. Subsequently, as an example for application, the obtained PGMA@FPBA was used as a dispersive solid‐phase extraction (d‐SPE) adsorbent for enrichment of quercetin in red wine. The results indicated that the facile‐prepared boronate‐affinity adsorbent has great potential application for separation and enrichment of cis‐diol‐containing biomolecules in complex samples.

Herein, a magnetic borate‐functionalized MXene composite with multiple boronic affinity sites was fabricated by embedding Fe3O4 nanoparticles with 4‐formylphenylboronic acid functionalized Ti3C2Tx nanosheets and served as sorbent for the simultaneous extraction of catecholamines (CAs) in urine samples. The morphology and structure of the magnetic materials were investigated using scanning microscopy, vibrating sample magnetometer, X‐ray photoelectron spectrometer, and X‐ray diffraction. The introduction of polyethyleneimine can amplify the bonded boronic acid groups, thereby effectively improving the adsorption capacities for CAs based on the multiple interactions of boronic affinity, hydrogen bonding, and metal coordination. The adsorption performance was investigated using the kinetics and isotherms models, and the main parameters that influence the extraction efficiency were optimized. Under the most favorable magnetic solid‐phase extraction condition, a sensitive method for the analysis of CAs in urine samples was developed by combining magnetic solid‐phase extraction conditions with high‐performance liquid chromatography detection. The findings illustrated that the proposed approach possessed a wide linearity range of 0.05–250 ng/mL with an acceptable correlation coefficient (R2 ≥ 0.9984) and detection limits of 0.010–0.015 ng/mL for the target CAs. The research not only provides a notable composite with multiple boronic affinity sites but also offers an effective and feasible measure for the detection of CAs in biological samples.

“…In particular, the silica surface is easily activated and can anchor various functional groups because of its abundant Si–OH groups [19, 20]. Boronic acid is also known as a typical adsorbent for catecholamine extraction because it can form cyclic esters with cis-diol compounds under alkaline conditions [21–24]. Thus, boronic acid-functionalized materials exhibit strong affinity toward cis-diol-containing compounds, which leads to their applications for various functional materials and tasks, such as diagnostic sensing, magnetic separation, and targeted drug delivery [25, 26].…”

Because dopamine (DA) is one of the most critical neurotransmitters that influence a wide variety of motivated human behaviors, it is necessary to develop a facile diagnostic tool that can quantify the physiological level. In this study, core–shell magnetic silica nanoparticles (Fe 3 O 4 @SiO 2 ) were prepared using a modified sol–gel reaction. The Fe 3 O 4 @SiO 2 were functionalized using 3-aminophenylboronic acid (APBA) via a facile and rapid synthetic route, hereafter referred to as Fe 3 O 4 @SiO 2 @APBA The resultant Fe 3 O 4 @SiO 2 @APBA not only adsorbed DA molecules, but also were easily separated from solution using a simple magnetic manipulation. The adsorbed amounts of DA by the Fe 3 O 4 @SiO 2 @APBA were quantified by measuring the changes in fluorescence intensity of polydopamine (at 463 nm) originated from the self-polymerized DA remained in the supernatant before and after the adsorption process. The Fe 3 O 4 @SiO 2 @APBA exhibited two-stage adsorption behavior for DA, and the maximal adsorption capacity was 108.46 μg/g at pH 8.5. Our particle system demonstrated the potential application for extracting compounds with cis-diols (including catechol amines) from the biological fluid.
