Abstract
DNA sequences are widely used for gene transfer into cells including a number of substrate surface‐based supporting systems, but due to its singular structure property profile, DNA also offers multiple options for noncanonical applications. The special case of using DNA and oligodeoxyribonucleotide (ODN) structures for surface functionalization of biomedical implants is summarized here with the major focus on (a) immobilization or anchoring of nucleic acid structures on substrate surfaces, (b) incorporation of biologically active molecules (BAM) into such systems, and (c) biological characteristics of the resulting surfacesin vitroandin vivo. Sterilizations issues, important for potential clinical applications, are also considered.
