Figure 5.

TEM images of aqueous suspensions (c = 0.05 mg mL⁻¹) of Me₂PE-Gly(2C16)C32-OH: in phosphate buffer at pH = 7.7 (a–c); and carbonate buffer at pH = 10.0 (d–f), at different magnifications; the inset in (b) is depicted in (c). The black asterisks in (d,e) point to larger lamellar sheets, whereas the white arrowheads point to smaller, round, disk-like objects. Samples were prepared at 22 °C and stained with uranyl acetate.
