Aptamers represent a distinct category of short nucleotide sequences or peptide molecules characterized by their ability to bind to specific targets with high precision. These molecules are predominantly synthesized through SELEX (Systematic Evolution of Ligands by Exponential Enrichment) technology. Recent findings indicate that aptamers may have significant applications in regenerative medicine, particularly in the domain of tissue repair. In comparison to other bioactive agents, aptamers exhibit superior specificity and affinity, are more readily accessible, and can be chemically modified, thereby presenting a promising avenue for the functionalization of tissue engineering materials in tissue repair applications. This review delineates the properties of aptamers and examines the methodologies and advancements related to aptamer-functionalized hydrogels, nanoparticles, and electrospun materials. It categorizes the four primary functions of aptamers in tissue repair, namely regeneration, delivery systems, anti-inflammatory actions, and pro-coagulation effects. Furthermore, the review explores the utilization of aptamer-functionalized tissue engineering materials in the repair of bone, nerve, and vascular tissues, highlighting the mechanisms by which aptamers facilitate tissue growth and repair through regenerative properties and their role in transporting substances that promote repair. Lastly, the review addresses the future prospects and challenges associated with the application of aptamers in tissue repair, offering novel insights and directions for further research and application in this domain.
