These days researchers are continuously developing Nano devices that can be useful to mankind.
Taking the research another step forward Professor Nadrian C. Seeman and his student Baoquan Ding has developed a DNA cassette through which a nanomechanical device can be inserted and function in a DNA array and allowing for the motion of the Nanorobotic arm.
According to the researchers it is very difficult to insert a device at a specific site in a DNA array and making it move or function at that site is even more difficult.
The developers also commented that their research can pave the way for creating nanoscale assembly lines so that more complex maneuvers can be executed.
The dimensions of the nanodevice are 110 x 30 x 2 nm.
The device emulates the process by which RNA are translated to create protein sequences. However in their case the signals that control the device are DNA and not RNA.
In the research work the two chemists created a framework that is the cassette that can be used to place the nanodevice at a particular location in the DNA array. They also stated that the control mechanism linked with the cassette can be altered and the same can be used to place the device at some other location in the array and do some other work.
The researchers visualized their results using atomic force microscopy (AFM), which permitted them to observe the structure undergoing half-rotation.
