Een tapping mode atomic force microscoop (AFM) methode voor de visualisatie van plasmide DNA, cytoplasmatische eiwitten en DNA-eiwitcomplexen is beschreven. De methode bestaat uit alternatieve benaderingen voor het bereiden van monsters voor AFM beeldvorming volgende biochemische manipulatie. DNA met specifieke eiwit interactie regio's zijn waargenomen in de buurt-fysiologische buffer omstandigheden.
