Advancing Polymeric Delivery Systems Amidst a Nucleic Acid Therapy Renaissance

Nucleic Acid Drugs and DNA-based Delivery Systems.

Nucleic acids are biologically active materials, and chemically modified nucleic acids are now being used in nucleic acid drugs. DNA, one of the two types of nucleic acids, can also be used as a material to construct DNA-based delivery systems, such as DNA hydrogel, for therapeutic compounds. Use of chemically modified nucleic acids would greatly increase the therapeutic potency of such DNA-bas...

New drug delivery systems based on polymeric silk fibroin

Nowadays, design and synthesis of efficient drug delivery systems are of vital importance in order to optimize the efficacy of therapeutics and reducing side effects. So far, many drug delivery systems have been designed, among them, natural polymer-based systems have attracted the most attention. Silk fibroin (SF) as a natural polymer have several unique properties including excellent biocompa...

Drug delivery systems based on nucleic acid nanostructures.

The field of DNA nanotechnology has progressed rapidly in recent years and hence a large variety of 1D-, 2D- and 3D DNA nanostructures with various sizes, geometries and shapes is readily accessible. DNA-based nanoobjects are fabricated by straight forward design and self-assembly processes allowing the exact positioning of functional moieties and the integration of other materials. At the same...

Delivery Systems for In Vivo Use of Nucleic Acid Drugs

The notorious biotechnological advance of the last few decades has allowed the development of experimental methods for understanding molecular mechanisms of genes and new therapeutic approaches. Gene therapy is maturing into a viable, practical method with the potential to cure a variety of human illnesses. Some nucleic-acid-based drugs are now available for controlling the progression of genet...
