DNA origami

DNA origami is a technique that uses the natural properties of DNA molecules to create precise, nanoscale structures. By designing specific sequences of DNA, scientists can fold a long strand into intended shapes, like boxes or patterns, with the help of shorter "staple" strands that hold it in place. This method allows for the construction of complex, customized nanostructures that can be used in medicine, electronics, and materials science. Essentially, DNA origami turns genetic material into a programmable building block for tiny, functional structures.
