New Findings on Nanotechnology Described by Investigators at Graduate School

May 6, 2014

By a News Reporter-Staff News Editor at Life Science Weekly -- Researchers detail new data in Nanotechnology. According to news originating from Beijing, People's Republic of China, by NewsRx correspondents, research stated, "Molecular-level security devices have raised ever-increasing interest in recent years to protect data and information from illegal invasion. Prior molecular keypad locks have an output signal dependent upon not only the appropriate combination but also the exact sequence of inputs, but it cannot be reset or reprogrammed."

Our news journalists obtained a quote from the research from Graduate School, "Here, a DNA-based security system with reset and never-reported reprogram function is successfully developed in proof-of-principle, with which one can change the password in case that the system is cracked. The previous password becomes invalid in the reprogrammed security system. Interestingly, more than one password is designed to permit multiple users to access. By harnessing the intrinsic merit of the different passwords, the system can distinguish different user who is endowed with prior authority."

According to the news editors, the research concluded: "The intelligent device is addressed on solid support and facilitates electronic processes, avoiding chemical accumulation in the system by simple removal of the electrode from the input solution and indicating a main avenue for its further development."
