Abstract:

As is known, DNA biosensors and DNA chips are now of great interest in life sciences, and they are being highlighted by molecular biologists and chemists because of their potential applications in biomedical fields, especially in disease diagnosis1^[1-3]. In addition, with the development of molecular biology there have been increasing demands for new microsample and convenient methods for DNA or gene studies. In most cases of these researches, an extremely important problem is usually to structure DNA-modified surfaces.
