Figure 2

Excitonic AND logic truth tables showing the logic values associated with the ON- (Logic Output: 1) or OFF- (Logic Output: 0) states for the attachment (Logic Input: 1) or absence (Logic Input: 0) of T1 or T2 onto/from the nanobreadboard. Adjacent to the truth table are bar plots representing the concentration normalized fluorescence emission at 668 nm (Logic Output) corresponding to each logic state for AND logic gate designs 1 (b) and 2 (c). The threshold windows are indicated by the shaded gray areas. The logic threshold defines the midpoint of the logic threshold window and is indicated by a red dashed line in each bar chart. All spectra were collected by exciting F at 450 nm. Spectra were normalized by nanobreadboard concentration (∼25 nM).
