- 論文の詳細を見る
Unique DNA network structures have been constructed, when DNA solutions (concentration range from 50 $\mu$g/ml to 500 $\mu$g/ml) are spread on mica and highly ordered pyrolytic graphite (HOPG) surfaces. The DNA network structures depend on the fixation time, solution concentration and substrate adhesion force. A novel structure having a hexagonal symmetry has been found on the HOPG surface for the first time. HOPG is one of the promising substrates for photoemission analysis without any charge up problem. Clear C (1s), N (1s), O (1s) and P (2p) peaks corresponding to DNA molecules can be detected.
