Outline of Final Research Achievements

Our purpose of this study is "deposition on a surface" and "scanning tunneling microscopy imaging" of single isolated biomolecules. To deposit biomolecules on surfaces, electrospray ionization method is used in this study. We have succeeded the deposition and single molecular imaging of long oligothiophene molecules and biomolecules.
