A Turbidity (as measured by absorbance (A) at 500 nm with 1 cm path length) versus log(9) for 10 in mixture with 1 (circles), 4 (triangles) and 3 (crosses) in water. For ease of comparison, the turbidity values for the case involving 3 are plotted after dividing by 2. B Physical electronic representation of a RS flip-flop integrated with a substantial array of logic elements corresponding to the 9-induced reversible membrane formation/collapse by redox pair 3/4 in the presence of 10. C, D Truth tables for the sequential and combinational logic components involved in part B. Input5 (9) is taken as ‘high’ (1) when its concentration is 10−4.5 M, and ‘low’ (0) when it is absent. Output3, the turbidity when (9) = 10−4.5 M, is taken as ‘high’ (1) when the absorbance is >0.4. Otherwise, Output3 is ‘low’ (0).
