We used atomic force microscopy ( AFM ) to study the dose - dependent change in conformational and mechanical properties of DNA treated with PT - ACRAMTU ( [ PtCl ( en ) ( ACRAMTU - S ) ] ( NO3 ) 2 , ( en = ethane - 1 , 2 - diamine , ACRAMTU = 1 - [ 2 - ( acridin - 9 - ylamino ) ethyl ] - 1 , 3 - dimethylthiourea .
 Chemical: PT - ACRAMTU; Chemical: ( [ PtCl ( en ) ( ACRAMTU - S ) ] ( NO3 ) 2; Chemical: ethane - 1 , 2 - diamine; Chemical: ACRAMTU; Chemical: 1 - [ 2 - ( acridin - 9 - ylamino ) ethyl ] - 1 , 3 - dimethylthiourea
