Molecular devices based on DNA

It is shown that DNA molecule can be used for construction of different electronic devices. The results of investigation of DNA conducting properties are presented. The method of DNA based nanowires is considered. It is shown that the conducting properties of DNA can be used for making electronic nanobiochips, which have advantages in comparison with optical one due to their miniaturization, execution speed, absence of marking and exactness. It is also demonstrated the possibility of memory and logic devices made from DNA.
