Aptamers, or synthetic nucleic acids, offer targeted drug delivery for diseases. This review explores aptamer applications, selection, and strategies for overcoming challenges in cell-specific therapeutic delivery.
Area of Science:
- Biotechnology
- Molecular Medicine
- Drug Delivery Systems
Background:
- Aptamers are synthetic nucleic acids with potential for targeted therapy.
- They can deliver various therapeutics like siRNAs and chemotherapeutics.
- Clinical use is limited by current challenges.
Purpose of the Study:
- To review aptamer applications in drug delivery.
- To discuss selection methods and conjugation strategies.
- To highlight challenges and solutions for intracellular delivery.
Main Methods:
- Review of current literature on aptamer-mediated drug delivery.
- Analysis of aptamer selection techniques (e.g., SELEX).
- Examination of conjugation methods for drug attachment.
Main Results:
- Aptamers enable cell-specific delivery of therapeutics.
- Various selection and conjugation strategies are available.
- Intracellular delivery remains a key challenge with ongoing solutions.
Conclusions:
- Aptamers show promise for targeted drug delivery.
