Aptamers comprise single-chain nucleic acids (DNA/RNA) or peptide molecules capable of interacting with precise targets through exceptional binding strength and molecular specificity.

Discovered through an in vitro selection process known as SELEX (Systematic Evolution of Ligands by Exponential Enrichment), aptamers offer several distinct advantages over traditional antibodies:
Through molecular design, aptamers demonstrate binding affinities matching or surpassing antibody performance across diverse targets, ranging from ions and organic compounds to cellular structures, viral particles, and extracellular vesicles.
Unlike antibodies, aptamers are chemically synthesized, ensuring high batch-to-batch consistency and superior stability under various environmental conditions (temperature, pH), allowing for easier storage and transport.
Chemical synthesis is generally more cost-effective and scalable than antibody production, making aptamers an economically attractive option for large-scale applications.
Aptamers can be easily modified with reporter molecules (e.g., fluorophores, nanoparticles) or integrated onto surfaces, facilitating diverse detection strategies.
The combination of aptamers' recognition power with microfluidics' analytical benefits creates highly efficient biosensing platforms. These systems leverage laminar flow and controlled mixing for precise target-aptamer interactions, often incorporating various detection principles:
Applications in Focus: Exosomes

Recent progress underscores these biosensors' adaptability. In cancer diagnostics, aptamer-functionalized microfluidic platforms are transforming exosome profiling. These nanoscale extracellular vesicles transport tumor-derived biomolecules and are vital for liquid biopsies. Conventional exosome isolation and detection approaches remain labor-intensive. Aptamer-microfluidic systems facilitate streamlined on-chip vesicle capture and ultra-sensitive analysis using signal enhancement strategies such as Hairpin Chain Reaction and Rolling Circle Amplification.
