Scientists Make DNA Scaffold Nanosuperconductors

This engineered 3D nanomaterial can be used in various scientific fields. For example, for

signal amplification in quantum sensorscalculations. Previously, it was possible to create only 1D and 2D structures; they looked like films or wires with superconductivity; they were obtained using the lithographic method.

Thanks to its structuralprogrammability, DNA can provide an assembly platform for creating engineered nanostructures. However, the fragility of DNA makes it unsuitable for functional devices and nanofabrication from inorganic materials. In this study, we showed how DNA serves as a scaffold for creating three-dimensional nanoscale architectures that can be completely converted into inorganic materials such as superconductors.

DNA structures are quite fragile, which leads tothe fact that they need to be strengthened with additional materials. DNA is just a scaffold that serves to build various nanoarchitectural materials, they can completely transform into inorganic structures, for example, superconductors.

The authors hope that three-dimensional superconductingnanostructures can find applications in signal amplifiers that increase the speed and accuracy of quantum computers, and in supersensitive magnetic field sensors for medical imaging and geological mapping.
