Self‐Assembly of Strongly Amphiphilic Janus Nanoparticles into Freestanding Membranes

, 2021
Amphiphilic nanoparticles can adsorb at interfaces between immiscible phases and form membranes. The ability to handle nanoparticle monolayers/bilayers as freestanding membranes independently from the interfaces on which they form can be of significant ...

Curvature-Mediated Assembly of Janus Nanoparticles on Membrane Vesicles

Nano Letters, 2018
Besides direct particle-particle interactions, nanoparticles adsorbed to biomembranes experience indirect interactions that are mediated by the membrane curvature arising from particle adsorption. In this Letter, we show that the curvature-mediated interactions of adsorbed Janus particles depend on the initial curvature of the membrane prior to ...
