Display of the non-linear relationship of FRE intensity as a function of light intensity and irradiation time. (A) Image of FRE as a function of light intensity varying from 0 to 100% with 100% the maximum light intensity. Irradiation time was constant (60 s). Fluorescein was coupled to four types of trimers (all terminated with 5′-DMT): ATT, CTT, GTT and TTT. (B) A plot of FRE (arbitrary unit) as a function of light intensity. Data were taken from the analysis of a total of 328 data points in the various regions of the oDNA chip. (C) Image of FRE as a function of irradiation time varying from 1 to 16 s. Light intensity was constant (100%). (D) A plot of FRE as a function of irradiation time. Data were taken from the analysis of a total of 108 data points in the various regions of the oDNA chip.
