Recently, with the discovery
of the RNA interference mechanism, transfection of various small nucleic acid
fragments (miRNA, siRNA, shRNA and plasmid DNA etc.) has been gradually gaining
importance and it is nowadays being used for silencing of the specific gene
regions causing many diseases. The barriers in delivery of therapeutic nucleic
acids, drug, DNA or protein vaccines, which are aimed to used in treatment of
many diseases, into tissue and cells restrict the developments in this field.
Consequently, polymer, inorganic and lipid-based biomaterials or composites
synthetized from aforementioned biomaterials are tailored through various
modification for the delivery of nucleic acids, drugs and DNA/protein vaccines.
Also, nanoparticles are able to be more functionalized by optimizing or
modifying them to reduce the toxic effects and to target cell being
transfected. In the development of new generation therapeutics; i) new nucleic acid types, ii) surpassing biological barriers
restricting transfection efficiency, iii)
synthesis of more functional nano-biomaterials are being intensively studied in vitro/in vivo conditions and promising developments are being
experienced. In this review article, different biomaterials are classified
depending on their structures, discussed in detail and reference studies
regarding therapeutic applications of these biomaterials are presented in the
light of recent developments in the literature.
