Stretched single DNA molecules were prepared on substrates by Langmuir-Blodgett (LB) method for the restriction site mapping. Stretched single Lambda DNA and EcoRI bound to the DNA were observed by scanning near-field optical microscope (SNOM). As a result, the specific binding sites of EcoRI on the Lambda DNA molecules were determined.
