Abstract: Systematic Evolution of Ligand Exponential Enrichment (SELEX) is involved to screen DNA/RNA aptamers that recognize a target molecule (including biomolecules such as nucleic acids, lipids, sugars, proteins, and peptides, hormones, low molecular weight chemical substances, toxic substances, ions, etc.). In general, in order to perform SELEX, a process of fixing a target molecule on a substrate or bead surface is required. In addition, since positive/negative monitoring is not possible in each round of a SELEX process to observe whether an aptamer library is actually well combined with a target substance, whether the SELEX process is proceeded correctly is checked by analyzing aptamers screened through several rounds. In order to remarkably solve these conventional problems and to construct a simpler and easier SELEX technique, the present disclosure provides a new SELEX technique using gold nanoparticles.
