A modified "dynamic molecular combing" (DMC) technique used for stretching double-stranded DNA is reported. DNA molecules were stretched on the silanized mica surface by this technique, its speed being precisely controlled with a computer. This approach combined the precise DNA stretching method with high resolution AFM imaging at nanometer scale, thus making it useful for DNA alignment manipulation and subsequent gene research.
