摘要
It is demonstrated that the mica surface covered with a nanometer-thick, well connected silane film can appreciably improve the lateral resolution of DNA molecules in comparison with that on bare mica using atomic force microscopy. A typical value width of 4 nm can be obtained. We propose that the nanometer dimensioned porous surface provides an approach to eliminate the hydrated salt layer associated with the condensation of DNA strands, and leads to the enhancement of lateral resolution.
