Protein reconstitution in giant vesicles

open access: yes, 2023
Life on Earth is diverse and ranges from unicellular organisms to multicellular creatures like humans. Although there are theories about how these organisms might have evolved, we understand little about how ‘life’ started from molecules.

Effect of Bilayer Thickness on Membrane Bending Rigidity

open access: yes, 2004
The bending rigidity $k_c$ of bilayer vesicles self-assembled from amphiphilic diblock copolymers has been measured using single and dual-micropipet techniques.

Pairwise hydrodynamic interactions and diffusion in a vesicle suspension [PDF]

open access: yes, 2014
The hydrodynamic interaction of two deformable vesicles in shear flow induces a net displacement, in most cases an increase of their distance in the transverse direction.

Giant vesicles

open access: yes, 2009
In the present study a novel approach to characterize lipid domains, which may provide binding sites for peripheral or integral membrane proteins, is demonstrated. In particular, analysis of fluorescence lifetimes of NBD-labeled lipid analogues was used to study lipid domains in Giant unilamellar vesicles (GUV) and – based on the GUV results – in the ...

Intercellular communication between artificial cells by allosteric amplification of a molecular signal

open access: yesNature Communications, 2020
The principles of intercellular communication in multicellular organisms can be explored using artificial cells. Here, the authors report on giant vesicles which can recognize diffused chemical signals and amplify the signal by synthetic enzymatic ...

Vesicle dynamics in elongation flow: Wrinkling instability and bud formation

open access: yes, 2007
We present experimental results on the relaxation dynamics of vesicles subjected to a time-dependent elongation flow. We observed and characterized a new instability, which results in the formation of higher order modes of the vesicle shape (wrinkles ...

Mechanism of cellular uptake of genotoxic silica nanoparticles. [PDF]

open access: yes, 2012
Mechanisms for cellular uptake of nanoparticles have important implications for nanoparticulate drug delivery and toxicity. We have explored the mechanism of uptake of amorphous silica nanoparticles of 14 nm diameter, which agglomerate in culture medium ...

Integrating Digital Technologies Into Biochemistry Education: A Decade of Efforts, Pandemic Impacts, and Emerging Insights

open access: yesBiochemistry and Molecular Biology Education, EarlyView.
ABSTRACT This review critically examines the integration of Digital Information and Communication Technologies (TDICs) in biochemistry education over the past decade, highlighting both the benefits and challenges from a critical theoretical perspective. A systematic review was conducted to identify relevant literature, followed by thematic analysis and

Nanoporous silica-based protocells at multiple scales for designs of life and nanomedicine. [PDF]

open access: yes, 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 ...

New opportunities for bioscaffold‐enabled spinal cord injury repair

open access: yesBMEMat, EarlyView.
Schematic illustration of bioscaffolds for spinal cord injury repair. We summarize the effects of bioscaffold properties on SCI repair, highlight different types of bioscaffolds, various fabrication strategies, and in vivo transformations for the clinical development of SCI‐repairing bioscaffolds.
