DNA molecules immobilized on mica surface by various methods have been observed by atomic force microscopy both in air and in liquid. Divalent cations and 3-aminopropyltriethoxysilane (APTES) modified mica surface have been used to immobilize the DNA molecules. Optimal DNA and divalent cations conce
