 Therefore, the use of biodegradable particles can also be used for cardiac tissue.The success of DNA nanotechnology in constructing artificially designed nanostructures out of nucleic acids such as DNA, combined with the demonstration of systems for DNA computing, has led to speculation that artificial nucleic acid nanodevices can be used to target drug delivery based upon directly sensing its environment.These methods make use of DNA solely as a structural material and a chemical, and do not make use of its biological role as the carrier of genetic information.
