abstract = {In a previous study (D. Ray, et al., J. Phys. Chem. Lett.,
2024, 15, 8108–8113), we found that an alternating
electric field considerably affects the location of the
crystallization boundary and the liquid–liquid phase
separation line as well as crystallization kinetics in
lysozyme solutions containing sodium thiocyanate(NaSCN). The
present study extends this work by investigating the
influence of the same electric field on the microscopic
appearance of lysozyme crystals as they form from a
supersaturated solution. We observe a variety of distinct
crystal morphologies, which we classify as single- and
multi-armcrystals, flower-like crystal structures, whiskers,
and sea-urchin crystals. Crystal morphologies exhibit
significant variations with changes in protein and salt
concentrations, and the electric field strongly altersthe
morphology-state diagram in the protein-versus-salt
concentration plane. This alteration is likely due to the
field effect on protein–protein interactions. We believe
the effect is mediated by the field enhancedadsorption of
SCN ions to the surface of lysozyme, ultimately driving the
observed changes in crystallization behavior. These findings
offer insights into how electric fields can be used to
control crystal formation and morphology in protein
systems.},
