Building fluorescent sensors for carbohydrates using template-directed polymerizations.

Area of Science:

• Analytical Chemistry
• Polymer Science
• Biomedical Engineering

Background:

• Custom fluorescent sensors offer broad applications, but their development is limited.
• Molecular imprinting provides specific binding sites but lacks suitable fluorescent reporters.
• Existing methods struggle to create fluorescent sensors with significant signal changes upon analyte binding.

Purpose of the Study:

• To design and synthesize a novel fluorescent monomer for creating molecularly imprinted fluorescent sensors.
• To develop sensitive fluorescent sensors for cis-diols, specifically D-fructose, using molecular imprinting.
• To overcome limitations in fluorescent tag development for molecularly imprinted sensors.

Main Methods:

• Synthesis of a novel fluorescent monomer (1) capable of responding to cis-diol binding.
• Preparation of molecularly imprinted polymers using the synthesized fluorescent monomer.
• Utilizing template-directed polymerization for creating specific binding sites for D-fructose.

Main Results:

• The synthesized monomer enabled the creation of fluorescent sensors for cis-diols.
• Imprinted polymers demonstrated high sensitivity towards the target template, D-fructose.
• Significant fluorescence intensity enhancement was observed upon D-fructose binding to the imprinted polymers.

Conclusions:

• The developed fluorescent monomer is effective for creating molecularly imprinted fluorescent sensors.
• This approach offers a promising pathway for sensitive and specific detection of carbohydrates like D-fructose.
• The study addresses the need for improved fluorescent reporters in molecular imprinting for sensor applications.
