Aptamers are small, single-stranded oligonucleotide or peptide that binds with attention to detail and coordinates with a target molecule . The selection of aptamers is a meticulous process using the SELEX method . Aptamers are versatile in their ability to bind to various molecules, differing by structure, function, and form . They can be preferable to antibodies for their excellent composition, endurance, and lack of denaturing . Their small size allows them to get inside tissue with greater efficiency . Aptamers are also produced through chemical processes, making them easy to make, multiply, and change .
