Methylene blue-catalyzed photodecomposition of guanine

Methylene Blue에 의한 guanine의 광분해 현상

1) The photodecomposition rate of guanine being catalized by methylene blue ws 53.7% in contrast with 9.3% that of dark control for 180 min. 2) In guanine control, the decomposition rate was very low. For 180 min., the rate was 8.1% in illuminated sample and 3.9% in non-illuminated sample. 3) The decomposition rate of methylene blue was obviously interfered by the existence of guanine. In guanine and methylene blue mixture solution, the net decomposition rate, excluding that of dark control ws 39.2% and in dye only solution, it was 48.5%.
