Figure 1. Schematic illustration of TRFIA for MBZ detection.
Figure 2. Synthetic route of hapten MBZ-H1 and MBZ-H2.
Figure 3. Computational chemistry parameters of MBZ, haptens MBZ-H1 and MBZ-H2 (A); distribution and gaps (ΔE) of the HOMO and LUMO for MBZ, haptens MBZ-H1 and MBZ-H2 (B); ESP surfaces of MBZ, haptens MBZ-H1 and MBZ-H2; (C) Mulliken charge distribution of MBZ, haptens MBZ-H1 and MBZ-H2. Only those atoms that are shared by these structures are displayed. Hydrogen atoms are not included.
