“…To this end, the work [135] has demonstrated that, if one wraps ssDNA around single-walled carbon nanotubes (SWNTs), the semiconducting behavior of latter is drastically changed after ssDNA modification, showing a clear charge-transfer process at room temperature. A further systematic investigation into the temperature dependence of the single-electron tunneling features in this SWNT-ssDNA system has led the authors [135] to a conclusion that it is the ssDNA wrapping around the SWNTs that helps create quantum dots in series.…”

Nucleic acids and proteins are not only biologically important polymers: They have recently been recognized as novel functional materials surpassing in many aspects the conventional ones. Although Herculean efforts have been undertaken to unravel fine functioning mechanisms of the biopolymers in question, there is still much more to be done. This particular paper presents the topic of biomolecular charge transport, with a particular focus on charge transfer/transport in DNA and protein molecules. Here the experimentally revealed details, as well as the presently available theories, of charge transfer/transport along these biopolymers are critically reviewed and analyzed. A summary of the active research in this field is also given, along with a number of practical recommendations.)Received: ((will be filled in by the editorial staff))Revised: ((will be filled in by the editorial staff))

“…This is induced by the transfer of the DNA electrons to the CNT under excitation by the light illumination, and it holds the promise of application development for DNA@CNT organic semiconductors as photoswitching nanobio devices. The formation of quantum dots at low temperatures has also been verified [31], and we are pursuing the possibilities that these unique properties of nanobio-electronics devices endow biosensing and DDS systems with innovative functions.…”

Recent years have brought about a rapid rise in research on applications in biological and medical fields including cell and tissue inactivation, sterilization and disinfection, blood coagulation, therapy, surgery, pharmaceuticals, biosensing, and biochips by exploiting low-pressure, atmospheric-pressure, and solution plasma processes. Many of the basic constituent materials of biological organisms are nanometer-scale in size, thus presenting the possibility of a growing field of science and technology focused on a fusion between "bio" and "nano" mechanisms; we are now in the germinal stage of a new era of next-generation applied research in the biological and medical applications of nanocarbons typified by fullerenes and carbon nanotubes. In this context, the authors have proposed and implemented research utilizing nanoscopic processes in advanced gas, liquid, and gas-liquid interfacial plasmas, directed toward the creation of synthetic materials and devices composed of nanocarbons, nanoparticles, and biomolecules. This research is positioned to advance the establishment of nano-bio fusion science opened and created with plasmas to construct next-generation nanobio and medical systems relating to nanobio-electronics devices, intracellular nanoengineering, and nanomedicine.

“…This was the result of electron transfer in the DNA hybrid molecule with increasing voltage [77]. Other important DNA-based nanoscale devices that have recently been developed include highly conductive nanowires [78], quantum dots with carbon nanotubules [79], and even radically advanced devices which detect single-nucleotide polymorphism and conduct nucleotide sequence mutation analysis [80]. With added progress in this field, it could be possible to use DNA-based electronics for both DNA-based diagnostics and sophisticated nanoscale electrical devices.…”

In addition to its genetic function, DNA is one of the most distinct and smart self-assembling nanomaterials. DNA nanotechnology exploits the predictable self-assembly of DNA oligonucleotides to design and assemble innovative and highly discrete nanostructures. Highly ordered DNA motifs are capable of providing an ultra-fine framework for the next generation of nanofabrications. The majority of these applications are based upon the complementarity of DNA base pairing: adenine with thymine, and guanine with cytosine. DNA provides an intelligent route for the creation of nanoarchitectures with programmable and predictable patterns. DNA strands twist along one helix for a number of bases before switching to the other helix by passing through a crossover junction. The association of two crossovers keeps the helices parallel and holds them tightly together, allowing the assembly of bigger structures. Because of the DNA molecule's unique and novel characteristics, it can easily be applied in a vast variety of multidisciplinary research areas like biomedicine, computer science, nano/optoelectronics, and bionanotechnology.
