A) Effect of complexation of polymers with oppositely charged probes on probe fluorescence; B) absorbance-matching of the fluorescent probes in the presence and absence of the complementary polymers; evolution of the C) absorption and D) fluorescence spectra of calcein upon titrating the calcein-P1 complex with Na₂SO₄; E) Molecular dynamics (MD) simulations on Mg²⁺ stabilization of a P2 bilayer; F), MD simulation: Mg²⁺ gluing action on an intrinsically instable P2 reverse bilayer. Followed by self-assembly energy (ΔE_ass) in kcal mol⁻¹ as a function of simulation time (values per-monomer).
