what are the top RNA aptamer companies?

Introduction to RNA Aptamers

RNA aptamers are short, single‐stranded RNA molecules that can fold into complex three-dimensional structures, thereby enabling them to bind specific target molecules with high affinity and specificity. In essence, these aptamers function similarly to antibodies but are entirely nucleic acid–based. Their modularity, ease of chemical modification, and amenability to in vitro selection make them powerful tools in diagnostics, therapeutics, and as carriers for targeted drug delivery. Due to their small size and synthetic origin, RNA aptamers exhibit low immunogenicity and can often be engineered for improved stability through chemical modifications such as 2′-O-methylation, 2′-fluoropyrimidine substitutions, or even PEGylation.

Historical Development and Applications 
The evolution of RNA aptamers dates back roughly to the early 1990s, when researchers first demonstrated that nucleic acids could be selected in vitro to bind protein targets with remarkable specificity and affinity. This achievement, using the SELEX (Systematic Evolution of Ligands by EXponential Enrichment) methodology, laid the foundation for what would become an expanding field encompassing both diagnostic and therapeutic applications. Over the years, aptamers have evolved from simple binding agents to sophisticated molecular tools. For example, they have found application in biosensor design, molecular imaging, and targeted delivery of therapeutics such as siRNA and chemotherapeutic drugs. The success of early aptamer drugs such as Macugen in the treatment of age-related macular degeneration has further validated their potential. As a result, aptamers continue to generate immense interest from both academia and industry, spurring significant research investment and technological innovation.
