Acoustically shaped DNA-programmable materials

This paper demonstrates a novel materials fabrication approach that combines DNA-programmable assembly with acoustic field control. This method allows for the creation of macroscale morphologies with nanoscale precision, overcoming a key challenge in DNA nanotechnology. Using microscopy and x-ray scattering, the authors reveal the nucleation, fusion, and growth processes under different acoustic conditions. The approach offers a pathway for fabricating complexly shaped macroscale morphologies for various DNA-programmable nanomaterials.
