Area of Science:

• Materials Science
• Supramolecular Chemistry
• Biochemistry

Background:

• Hydrogels are versatile materials with applications in drug delivery and tissue engineering.
• Developing novel hydrogels with advanced properties like self-healing and antimicrobial activity is an active research area.
• Cytidine and boronic acids are biocompatible building blocks with potential for supramolecular assembly.

Purpose of the Study:

• To prepare novel hydrogels using silver ion-induced assembly of cytidine and boronic acids.
• To investigate the structural, mechanical, and functional properties of the resulting hydrogels.
• To explore the potential applications of these hydrogels as antimicrobial agents and drug delivery systems.

Main Methods:

• Hydrogel formation via silver ion (Ag+) induced self-assembly of cytidine and boronic acid derivatives.
• Characterization of hydrogel properties including thixotropy and self-healing.
• Evaluation of antimicrobial activity against relevant pathogens.
• Tuning of antimicrobial efficacy by modifying the boronic acid component.

Main Results:

• Successfully synthesized hydrogels through Ag+ ion-mediated assembly.
• The hydrogels demonstrated significant thixotropic and self-healing capabilities, indicative of dynamic supramolecular structures.
• Potent antimicrobial activity was observed, which could be modulated by altering the functional groups on the boronic acid.
• The cytidine-boronic acid hydrogels show promise for stimuli-responsive drug delivery.

Conclusions:

• Ag+ ion-induced assembly of cytidine and boronic acids provides a facile route to novel hydrogels.
• These hydrogels possess desirable mechanical properties (thixotropy, self-healing) and tunable antimicrobial activity.
• The developed hydrogels represent a promising platform for advanced antimicrobial therapies and smart drug delivery systems.
