The research in the field of biomaterials has largely focused on the development of methods to enhance their bioactivity. Adopted strategies include chemical-physical approaches, but mainly the use of monoclonal antibodies, which confer the system target specificity. However, antibodies are marred by numerous issues, such as low physical-chemical stability or the risk of inducing immunological responses in the host, which often make their use difficult. Aptamers – a new class of molecules discovered in the early nineties – are small oligonucleotides, or in some cases peptides, and have been proposed to rival antibodies in biomedicine, countering at least some of the antibody-related drawbacks. The aim of this review is to provide a background to nucleic acid aptamers and to explore their novel applications. In addition to providing brief overview of their therapeutics applications, here we have assessed the methods that employ aptamers to improve the bioactivity of biomaterials, in particular, those that enhance targeting properties of drug delivery systems for chemotherapy, and those ameliorating scaffold biocompatibility for tissue engineering approaches.
