摘要

We report oil the specific interaction between DNA and some mica-family minerals and other layered silicate structures. The interaction depends on mineral surfaces's crystallography, chemistry and potential. These properties are responsible for a remarkable variety of adsorption mechanisms and can be used to modulate surface self-assembly and nanopatterning of DNA. The controlled deposition of DNA onto non-conductive mineral regions with atomically flat boundaries has very attractive applications in nano-biotechnology (for example. microelectronics, microarrays and sensors). In addition. the extreme affinity discovered for some mineral surfaces, together with their ability to organize the DNA molecules. could be an indication of their catalytic potential. It may also have had relevance in the prebiotic environment, with important implications for the earth and life sciences.
