Ionic Solvent Shell Drives Electroactuation in Organic Mixed Ionic‐Electronic Conductors [PDF]

Advanced Science
The conversion of electrochemical processes into mechanical deformation in organic mixed ionic‐electronic conductors (OMIECs) enables artificial muscle‐like actuators but is also critical for degradation processes affecting OMIEC‐based devices.

Electroformation of Giant Vesicles on Indium Tin Oxide (ITO)-Coated Poly(ethylene terephthalate) (PET) Electrodes [PDF]

Membranes, 2011
Electroformation of cell-sized lipid membrane vesicles (giant vesicles, GVs) from egg yolk phosphatidylcholine was examined using a poly(ethylene terephthalate) sheet coated with indium tin oxide (ITO-PET) as the electrode material.

Electroformation of Giant Unilamellar Vesicles on Stainless Steel Electrodes. [PDF]

ACS Omega, 2017
Giant unilamellar vesicles (GUVs) are well-established model systems for studying membrane structure and dynamics. Electroformation, also referred to as electroswelling, is one of the most prevalent methods for producing GUVs, as it enables modulation of

Investigation of Transport in OECTs with Electrochemical Strain Wave Microscopy [PDF]

Small, Volume 21, Issue 52, December 29, 2025.
Electrochemical strain waves (ESWs) are generated in mixed conductors by alternating charge injection at a contacting electrode. They propagate into the device channel through combined charge transport and swelling. AFM experiments map the local amplitude and phase of ESWs in organic electrochemical transistors (OECTs), providing quantitative insight ...

Photomanipulation of Minimal Synthetic Cells: Area Increase, Softening, and Interleaflet Coupling of Membrane Models Doped with Azobenzene‐Lipid Photoswitches [PDF]

Advanced Science, Volume 10, Issue 31, November 3, 2023., 2023
Using giant unilamellar vesicles, Langmuir monolayers, supported lipid bilayers, and molecular dynamics simulations it is shown that membranes doped with the photoswitchable lipid azobenzene‐phosphatidylcholine (azo‐PC) can increase their area by ≈25%, undergo a ten‐fold decrease in bending rigidity, become thinner, and increase their specific membrane

Photoswitchable Endocytosis of Biomolecular Condensates in Giant Vesicles [PDF]

Advanced Science, Volume 11, Issue 23, June 19, 2024.
This work demonstrates efficient, rapid and reversible light‐guided modulation of membrane‐condensate interactions. Using giant unilamellar vesicles (GUVs) doped with the photolipid azo‐PC, membrane‐condensate wetting transitions are induced and characterized, enabling swift endocytosis over multiple cycles.

Lipid peroxides promote large rafts: effects of excitation of probes in fluorescence microscopy and electrochemical reactions during vesicle formation. [PDF]

Biophys J, 2006
Raft formation and enlargement was investigated in liposomes and supported bilayers prepared from sphingomyelin (SM), cholesterol, and unsaturated phospholipids; NBD-DPPE and rhodamine-(DOPE) were employed as fluorescent probes.

Effects of SOPC on the Phase Behaviors of the DSPC/DOPC/Cholesterol Biomembrane Model System [PDF]

, 2007
The phase diagram of the DSPC/DOPC/cholesterol biomembrane model system was recently determined by studies in our laboratory. However, the component DOPC does not occur in animal cell plasma membranes, but was chosen for convenience in solving the phase
