Probing lipid membrane bending mechanics using gold nanorod tracking
Mehdi Molaei, Sreeja Kutti Kandy, Zachary T. Graber +3
Lipid bilayer membranes undergo rapid bending undulations with wavelengths from tens of nanometers to tens of microns due to thermal fluctuations. Here, we probe such undulations a…
Excess area dependent scaling behavior of nano-sized membrane tethers
N. Ramakrishnan, Arpita Roychoudhury, David M. Eckmann +6
Thermal fluctuations in cell membranes manifest as an excess area () which governs a multitude of physical process at the sub-micron scale. We present a theoreti…
Curvature-driven migration of colloids on lipid bilayers
Ningwei Li, Nima Sharifi-Mood, Fuquan Tu +4
Colloids and proteins alike can bind to lipid bilayers and move laterally in these two-dimensional fluids. Inspired by proteins that generate membrane curvature, sense the underlyi…
Application of a Free Energy Landscape Approach to Study Tension Dependent Bilayer Tubulation Mediated by Curvature Inducing Proteins
Richard W. Tourdot, N. Ramakrishnan, Tobias Baumgart +1
We investigate the phenomenon of protein induced tubulation of lipid bilayer membranes within a continuum framework using Monte Carlo simulations coupled with the Widom insertion t…
Exploiting imperfections: Directed assembly of surface colloids via bulk topological defects
Marcello Cavallaro, Mohamed A. Gharbi, Daniel A. Beller +6
We exploit the long-ranged elastic fields inherent to confined nematic liquid crystals to assemble colloidal particles trapped at the liquid crystal interface into reconfigurable s…
Ring around the colloid
Marcello Cavallaro, Mohamed A. Gharbi, Daniel A. Beller +6
In this work, we show that Janus washers, genus-one colloids with hybrid anchoring conditions, form topologically required defects in nematic liquid crystals. Experiments under cro…
