Synthesis and Characterization of Boronate Affinity Three-Dimensionally Ordered Macroporous Materials

Area of Science:

• Materials Science
• Analytical Chemistry
• Biochemistry

Background:

• Sample pretreatment is crucial for analyzing trace substances in complex matrices.
• Cis-dihydroxyl (cis-diol) containing compounds are prevalent in biological samples.
• Boronate affinity adsorbents offer selective binding for cis-diol groups.

Purpose of the Study:

• To develop novel spherical three-dimensionally ordered macropore (3DOM) materials.
• To utilize boronate affinity and colloidal crystal templating for material synthesis.
• To evaluate the material's performance in separation and enrichment applications.

Main Methods:

• Synthesis of 3DOM materials using colloidal crystal templating and boronate affinity.
• Characterization via FTIR, SEM, XPS, and TGA.
• Adsorption studies with ovalbumin (OVA) and adenosine.
• Electrophoresis analysis of egg white proteins.

Main Results:

• The 3DOM materials exhibited high specific surface area, porosity, and boronic acid sites.
• Maximum adsorption capacity for OVA reached 438.79 mg/g.
• Demonstrated high affinity and selectivity for OVA and adenosine.
• Successfully separated and enriched glycoproteins from egg white samples.

Conclusions:

• A novel boronate affinity 3DOM material with ordered pore structure was successfully prepared.
• The material shows excellent selectivity, efficiency, and high throughput for cis-diol group separation.
• This material holds potential for applications in complex sample analysis and purification.
