abstract = {The self-assembly of the two anomeric forms of
n-hexadecyl-d-maltopyranoside (denoted α-C16G2 and
β-C16G2) has been studied in dilute aqueous solution by
means of surface tension measurements, scattering methods
(dynamic light scattering, static light scattering, and
small-angle X-ray and neutron scattering), and
cryo-transmission electron microscopy at different
surfactant concentrations and temperatures. Surface tension
measurements demonstrate differences in the surfactant
adsorption at the air–water interface, where α-C16G2
shows a lower CMC than β-C16G2. Similarly, micelle
morphology was found to profoundly depend on anomerism.
β-C16G2 preferentially forms very elongated micelles with
large persistence lengths, whereas α-C16G2 assembles into
smaller micelles for which the structure varies with
concentration and temperature. The differences between the
two surfactant anomers in terms of self-assembly can be
attributed to the interaction between neighboring
headgroups. Specifically, β-C16G2 allows for a closer
packing in the palisade layer, hence reducing the micelle
curvature and promoting the formation of more elongated
micelles. Strong intermolecular headgroup interactions may
also account for the observed rigidity of the micelles.},
