Being a natural polymer, DNA attracts extensive attention and possesses great potential to open a new way for researches of biomedical or material science. In the past few decades, approaches have been developed to bring DNA into the realm of bulk materials. In this review, we discussed the progresses achieved for fabrication of novel materials with a large physical dimension from the DNA polymer.
