A DNA nanotechnology is an innovative field of research that uses DNA molecules to design and build nanoscale structures and devices. By exploiting the unique properties of DNA, such as its ability to self-assemble and store genetic information, scientists can construct nanoscale materials with specific, programmable functions. DNA nanotechnology combines the disciplines of molecular biology, nanotechnology, and materials science to create new types of molecular machines, sensors, and structures for use in a wide range of applications, including drug delivery, biosensing, biotechnology, and nanomedicine
