Chemical communication at the synthetic cell/living cell interface
Communications Chemistry, 2021 Synthetic models of cells are becoming increasingly sophisticated, but engineering communication between these and living cells remains challenging. Here the authors review modes of communication and signal processing between living cells and synthetic ...

Shear stress induced lipid order and permeability changes of giant unilamellar vesicles.
Biochimica et Biophysica Acta - General Subjects, 2022 BACKGROUND The permeability of a lipid bilayer is a function of its phase state and depends non-linearly on thermodynamic variables such as temperature, pressure or pH.

Pulling Membrane Nanotubes from Giant Unilamellar Vesicles [PDF]
Journal of Visualized Experiments, 2017 The reshaping of the cell membrane is an integral part of many cellular phenomena, such as endocytosis, trafficking, the formation of filopodia, etc. Many different proteins associate with curved membranes because of their ability to sense or induce membrane curvature.

Production of giant unilamellar vesicles and encapsulation of lyotropic nematic liquid crystals.
Soft Matter, 2021 We describe a modified microfluidic method for making Giant Unilamellar Vesicles (GUVs) via water/octanol-lipid/water double emulsion droplets. At a high enough lipid concentration we show that the de-wetting of the octanol from these droplets occurs ...

Programmed magnetic manipulation of vesicles into spatially coded prototissue architectures arrays
Nature Communications, 2020 To execute higher-order functions, cells self-assemble into spatially coded tissue configurations. Here the authors magnetically assembly giant unilamellar vesicles into three dimensional tissue-mimic structures with collective osmotic stability.

Magnetoliposomes as model for signal transmission [PDF]
Royal Society Open Science, 2019 Liposomes containing magnetic nanoparticles (magnetoliposomes) have been extensively explored for targeted drug delivery. However, the magnetic effect of nanoparticles movement is also an attractive choice for the conduction of signals in communication ...

Nanoporous silica-based protocells at multiple scales for designs of life and nanomedicine. [PDF]
, 2015 Various protocell models have been constructed de novo with the bottom-up approach. Here we describe a silica-based protocell composed of a nanoporous amorphous silica core encapsulated within a lipid bilayer built by self-assembly that provides for ...

Thermodynamic relaxation drives expulsion in giant unilamellar vesicles [PDF]
Physical Biology, 2009 We investigated the thermodynamic relaxation of giant unilamellar vesicles (GUVs) which contained small vesicles within their interior. Quenching these vesicles from their fluid phase (T>Tm) through the phase transition in the gel state ...
