A reversibly gated protein-transporting membrane channel made of DNA

open access: yesNature Communications, 2022
Artificial systems to control the transport of molecules across biomembranes can be useful for biosensing or drug delivery. Here, the authors assemble a DNA channel enabling the precisely timed, stimulus-controlled transport of functional proteins across

Tuning ubiquinone position in biomimetic monolayer membranes [PDF]

open access: yes, 2017
Artificial lipid bilayers have been extensively studied as models that mimic natural membranes (biomimetic membranes). Several attempts of biomimetic membranes inserting ubiquinone (UQ) have been performed to enlighten which the position of UQ in the ...

Spatial arrangement of proteins in planar and curved membranes by PPM 3.0

open access: yesProtein Science, 2021
Cellular protrusions, invaginations, and many intracellular organelles have strongly curved membrane regions. Transmembrane and peripheral membrane proteins that induce, sense, or stabilize such regions cannot be properly fitted into a single flat ...

Effects of Expanded Hemodialysis with Medium Cut-Off Membranes on Maintenance Hemodialysis Patients: A Review

open access: yesMembranes, 2022
Kidney failure is associated with high morbidity and mortality. Hemodialysis, the most prevalent modality of renal replacement therapy, uses the principle of semipermeable membranes to remove solutes and water in the plasma of patients with kidney ...

How Does Carbon Dioxide Permeate Cell Membranes?A discussion of concepts, results and methods.

open access: yesFrontiers in Physiology, 2014
We review briefly how the thinking about the permeation of gases, especially CO2, across cell and artificial lipid membranes has evolved during the last hundred years.

Preparation of artificial plasma membrane mimicking vesicles with lipid asymmetry. [PDF]

open access: yesPLoS ONE, 2014
Lipid asymmetry, the difference in lipid distribution across the lipid bilayer, is one of the most important features of eukaryotic cellular membranes.

Catalytic molecularly imprinted polymer membranes: Development of the biomimetic sensor for phenols detection [PDF]

open access: yes, 2010
Portable biomimetic sensor devices for the express control of phenols content in water were developed. The synthetic binding sites mimicking active site of the enzyme tyrosinase were formed in the structure of free-standing molecularly imprinted ...

Toward Artificial Mitochondrion: Mimicking Oxidative Phosphorylation in Polymer and Hybrid Membranes.

open access: yesNano letters (Print), 2017
For energy supply to biomimetic constructs, a complex chemical energy-driven ATP-generating artificial system was built. The system was assembled with bottom-up detergent-mediated reconstitution of an ATP synthase and a terminal oxidase into two types of
