Abstract
Two experimental methods for materialization of DNA as novel molecular devices are described. Two types of Langmuir monolayers complexed with DNA molecules at the air-water interface were prepared for single-DNA stretching and template polymerization of the DNA-mimetics, respectively. Single-DNA molecule can be stretched on the solid surface when the ionic complex of a double-stranded DNA and a cationic monolayer was transferred slowly from water surface to the hydrophilic solid surface by using conventional Langmuir-Blodgett technique. The surface monolayer of the diacetylene containing nucleobase amphiphiles prepared as DNA-mimetics can form complementary hydrogen bonds with single-stranded DNAs at the air-water interface. The single-stranded DNA molecule can act as a template of photopolymerization of the diacetylene groups in the DNA-mimetics. Combination of two methods will provide a new preparation strategy of single molecular devices based on DNA.
