Interaction energy profiles between S. mutans and discs. (A) Modeled components of the total interaction energy (ΔG) from the xDLVO theory (LW: Lifshitz–van der Waals interactions; EL: electrostatic interactions; AB: Lewis acid-base interactions) for control and 30 wt% BTO-nanocomposite discs. (B) Energy profiles of the sum of LW and EL (DLVO components) depict a larger repulsive energy barrier for interaction between S. mutans and 30 wt% BTO-nanocomposite discs. (C) Total interaction energy (LW+EL+AB) for control and 30 wt% BTO-nanocomposite discs. Inset depicts a magnification of the profiles between separation distances of 2 to 4 nm (n≥3).
