Area of Science:

  • Biomaterials Science
  • Drug Delivery Systems
  • Molecular Engineering

Background:

  • Hydrogels are widely used in biomedical applications due to their biocompatibility and tunable properties.
  • Sustained-release drug delivery systems aim to maintain therapeutic drug concentrations over extended periods, improving patient compliance and efficacy.
  • DNA aptamers offer high specificity and affinity for target molecules, making them promising candidates for controlled release applications.

Purpose of the Study:

  • To investigate the potential of functionalizing hydrogels with DNA aptamers for developing a novel sustained-release system.
  • To evaluate the performance of aptamer-functionalized hydrogels in controlling the release kinetics of therapeutic agents.

Main Methods:

  • Hydrogel synthesis and characterization.
  • Functionalization of hydrogels with specific DNA aptamers.
  • In vitro drug release studies to assess release profiles.
  • Evaluation of aptamer-hydrogel interactions and stability.

Main Results:

  • Successful functionalization of hydrogels with DNA aptamers was achieved.
  • Aptamer-modified hydrogels demonstrated controlled and sustained release of loaded therapeutic agents.
  • The release rate was influenced by the aptamer density and binding affinity within the hydrogel matrix.

Conclusions:

  • Hydrogel functionalization with DNA aptamers presents a viable strategy for developing advanced sustained-release drug delivery systems.
  • This approach offers a promising platform for targeted and prolonged delivery of therapeutics.
  • Further research can explore specific aptamer-drug conjugates and diverse hydrogel compositions for optimized performance.
