摘要

Researchers at Massachusetts Institute of Technology and Virginia Commonwealth University, USA, reckon their supramolecular nanostamping printing technique could enable the mass production of nanodevices. The method uses DNA hybridization to replicate a pattern and has a resolution of less than 40 nm. Initially, the scientists believe their nano-printing method might be of benefit in making DNA microarrays. Currently manufacturing these devices requires at least 400 printing steps and costs around 500 dollars per microarray. But supramolecular nanostamping would need only three steps and could reduce the cost of each microarray to less than 50 dollars. "This would completely revolutionize diagnostics." said Francesco Stellacci of MIT. "The more we test with microarrays, the more we know about illnesses and the more we can detect."
