We demonstrate a new approach to pattern transfer for bottom-up nanofabrication. We show that DNA promotes/inhibits the etching of SiO(2) at the single-molecule level, resulting in negative/positive tone pattern transfers from DNA to the SiO(2) substrate.
我们展示了一种新的自下而上纳米制造中图案转移的方法。我们表明，DNA 在单分子水平上促进/抑制了 SiO(2)的刻蚀，从而导致 DNA 到 SiO(2)衬底的负/正色调图案转移。
