Abstract:
Background: Aptamers are short single-stranded oligonucleotides; due to their 3D structure,
they can specifically bind to various targets. They can target several molecules ranging from metal
ions, organic components to proteins, and large cells.
Methods: According to the high affinity of aptamers, they can be used for diagnosis, therapeutic, vaccine
development, and gene silencing applications. The conventional method for aptamer selection is
known as the Systematic Evolution of Ligands by Exponential (SELEX). However, despite the efficiency
of SELEX as a screening procedure, it is beneficial to develop more rational procedures for aptamer
selection.
Results & Discussion: Herein, in silico approaches can play an effective role given their potential in
representing an efficient, cost-effective, parallelizable, and rapid strategy. In recent years, several attempts
have been applied to develop algorithms and software for the rational selection of aptamers.
However, there is still a need for more efforts to achieve the most efficient techniques in this area.
Conclusion: In this review, we aim to overview different computational approaches that are used for
aptamer selection.
