The controlled manipulation of matter using radiation pressure, otherwise known as optical
trapping, has emerged as a powerful experimental tool in the physical sciences. One …

Motivated by the motion of biopolymers and membranes in solution, this article presents a
formulation of the equations of motion for curves and surfaces in a viscous fluid. The focus is …

Vesicles consisting of a bilayer membrane of amphiphilic lipid molecules are remarkably
flexible surfaces that show an amazing variety of shapes of different symmetry and topology …

The shape dynamics of fluid vesicles is governed by the coupling of the flow within the two-
dimensional membrane to the hydrodynamics of the surrounding bulk fluid. We present a …

Fluid deformable surfaces are ubiquitous in cell and tissue biology, including lipid bilayers,
the actomyosin cortex or epithelial cell sheets. These interfaces exhibit a complex interplay …

Due to surface tension, a beading instability takes place in a long enough fluid column that
results in the breakup of the column and the formation of smaller packets with the same …

Neuronal axons must navigate a mechanically heterogeneous environment to reach their
targets, but the biophysical mechanisms coupling mechanosensation, growth, and …

We have studied the pearling instability induced on hollow tubular lipid vesicles by
hydrophilic polymers with hydrophobic side groups along the backbone. The results show …

We review the dynamical behavior of giant fluid vesicles in various types of external
hydrodynamic flow. The interplay between stresses arising from membrane elasticity …

Current research into the morphology of lipid membranes focuses on three areas: first, the
transformations and fluctuations of the shape of freely suspended vesicles; second, the …
