UV/vis/NIR absorption spectra of the polymerisation products. The products were obtained upon oxidation and polymerisation of aniline (4.0 mM) at pH = 4.3 (20 mM NaH₂PO₄) with HRP (0.92 μM) and H₂O₂ (4.5 mM) for 24 h at 25 °C in the presence of LUVs formed from either a DOPC; b DOPA, DOPG, or DOPS; c bovine brain sulfatides, SDBS/DA (1:1), or AOT. For all these measurements, the amphiphile concentration was 3.0 mM. Path length (L): 0.1 cm. The spectrum recorded for a reaction mixture which did not contain vesicles is also shown in (a). The chemical structures of the head group of each amphiphile are given as insets
