Nucleic Acid Aptamers as Emerging Tools for Diagnostics and Theranostics.

Area of Science:

• Biotechnology
• Molecular Biology
• Nucleic Acid Chemistry

Background:

• Aptamers are single-stranded DNA or RNA molecules (20-80 nucleotides) generated in vitro.
• Systematic Evolution of Ligands using EXponential enrichment (SELEX) is the primary method for aptamer generation.
• Aptamers bind targets with high affinity and specificity, enabling applications in diagnostics and therapeutics.

Purpose of the Study:

• To describe methods for generating DNA aptamers against protein targets.
• To highlight the theranostic potential of DNA aptamers.

Main Methods:

• In vitro selection (SELEX) process for DNA aptamer generation.
• Characterization of aptamer-target interactions.
• Evaluation of aptamer utility in theranostic applications.

Main Results:

• Successful generation of DNA aptamers against specific protein targets.
• Demonstration of tunable affinity and specificity of generated aptamers.
• Potential applications in theranostics, combining diagnostics and therapeutics.

Conclusions:

• DNA aptamers can be effectively generated against protein targets using SELEX.
• Aptamers offer a versatile platform for developing novel diagnostic probes and therapeutic ligands.
• The described methods facilitate the advancement of aptamer-based theranostics.
