DNA Machines and Nanobots

The robust ability of DNA to self-assemble into miscellaneous nanostructures, as it was described in the previous chapter, can also be employed for the construction of molecular size active nanomechanical devices and nanorobots, aka molecular machines or nanomachines, made entirely or partially of DNA. This idea is so inspiring that in the past decade there was a burst of activity in the area of DNA machines: a diverse variety of them have been designed based on several different principles, and their workability has been proved using different physical techniques.
