Temperature-Promoted Giant Unilamellar Vesicle (GUV) Aggregation: A Way of Multicellular Formation

open access: yesCurrent Issues in Molecular Biology, 2023
The evolution of unicellular to multicellular life is considered to be an important step in the origin of life, and it is crucial to study the influence of environmental factors on this process through cell models in the laboratory.

GUV preparation and imaging: Minimizing artifacts

open access: yesBiochimica et Biophysica Acta (BBA) - Biomembranes, 2010
The components of biological membranes are present in a physical mixture. The nonrandom ways that the molecules of lipids and proteins mix together can strongly influence the association of proteins with each other, and the chemical reactions that occur in the membrane, or that are mediated by the membrane.

Semisynthesis of functional transmembrane proteins in GUVs [PDF]

open access: yes, 2021
Abstract Cellular transmembrane (TM) proteins are essential sentries of the cell facilitating cell-cell communication, internal signaling, and solute transport. Reconstituting functional TM proteins into model membranes remains a challenge due to the difficulty of expressing hydrophobic TM domains and the required use of detergents ...

Self‐Assembled Lipids as Soft Dielectrics

open access: yesAdvanced Functional Materials, EarlyView.
Self‐assembled lipid bilayers serve as soft dielectric materials for ultrathin electronics. Using liquid‐metal parallel‐plate junctions, the capacitance and dielectric breakdown of dehydrated lipid films are characterized. Dielectric behavior is controlled by lipid molecular structure, cholesterol content, and assembly conditions, providing molecular ...

Azobenzene's Cross‐Scale Optics and Photonics: Molecular Photoswitching, Mesoscopic Material Motions, and Adaptive Devices

open access: yesAdvanced Materials, EarlyView.
Azobenzene photoswitches translate molecular‐scale E/Z photoisomerization into macroscopic material responses and device‐level photonic functions. This Review highlights how azobenzene research has evolved from molecular photochemistry to photoalignment, mass migration, photomechanics, and heat release, ultimately enabling holography, reconfigurable ...

β‐Ketonitrile‐Modified Prodan Derivatives as Large‐Stokes‐Shift Solvatochromic Fluorophores With Enhanced Brightness and Ratiometric Thermometric Response

open access: yesChemistry – A European Journal, EarlyView.
We report a systematic study of β‐ketonitrile–modified Prodan‐type solvatochromic fluorophores. The β‐ketonitrile substitution induces marked bathochromic shifts in absorption and emission and significantly enhances fluorescence quantum yields in nonpolar solvents.

Uniform Microscale Thermoresponsive Liposomes for Controlled Release Above Body Temperature

open access: yesSmall, EarlyView.
Uniform thermoresponsive liposomes are generated using a scalable double‐emulsion microfluidic approach coupled with accelerated solvent extraction. The resulting liposomes remain stable at physiological temperature but undergo abrupt rupture and cargo release at 41°C–45°C, providing a versatile platform for thermally triggered controlled release in ...

Dramatic morphological changes in liposomes induced by peptide nanofibers reversibly polymerized and depolymerized by the photoisomerization of spiropyran

open access: yesFrontiers in Molecular Biosciences, 2023
Cytoskeletons such as microtubules and actin filaments are natural protein assemblies, which dynamically control cellular morphology by reversible polymerization/depolymerization.
