Abstract: In the present invention, an electric field is created in the DNA solution while DNA is deposited on a polymer surface. A method of electric field assisted deposition of DNA on polymer surface according to an exemplary embodiment of the present invention comprises: forming a polymethylmethacrylate (PMMA) film on a silicon wafer by spin casting; preparing a DNA solution including DNA to be deposited on the PMMA film; and depositing DNA on the PMMA film by creating an electric field in the DNA solution while the silicon wafer on which the PMMA film is formed is submerged in the DNA solution.
