Fig. 6

Response of various sensors of: (A) BUP-TPB as function of log concentration of (a) BUP and (b) NAL, (B) BUP-TFMPB as function of log concentration of (c) BUP and (d) NAL, where values between parentheses represent the slope in (a, c) figures, and slope and (Log K^pot_{Drug, I}) in (b, d) figures.
