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

Advanced 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

Chemistry – 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.

Functional reconstitution of a voltage-gated potassium channel in giant unilamellar vesicles. [PDF]

PLoS ONE, 2011
Voltage-gated ion channels are key players in cellular excitability. Recent studies suggest that their behavior can depend strongly on the membrane lipid composition and physical state. In vivo studies of membrane/channel and channel/channel interactions

Membrane Manipulation of Giant Unilamellar Polymer Vesicles with a Temperature‐Responsive Polymer

Angewandte Chemie, 2022
Understanding the complex behavior and dynamics of cellular membranes is integral to gain insight into cellular division and fusion processes. Bottom‐up synthetic cells are as a platform for replicating and probing cellular behavior.

Uniform Microscale Thermoresponsive Liposomes for Controlled Release Above Body Temperature

Small, 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 ...

Reduced colony‐stimulating factor 1 receptor expression in myeloid cells has limited impact on chronic lymphocytic leukaemia progression

British Journal of Haematology, EarlyView.
Summary Targeting the colony‐stimulating factor 1 receptor (CSF1R) to remove tumour‐associated macrophages is being explored as cancer therapy. This strategy may be relevant for chronic lymphocytic leukaemia (CLL), which strongly depends on support from myeloid cells.

Diphtheria toxin T-domain as a tool for inducing lipid vesicle fusion

Communications Chemistry
Membrane fusion is fundamental for many biological processes, including subcellular compartmentalization, cell growth, and exo- and endocytosis. It also plays a key role in the fabrication of artificial membrane structures, particularly vesicles. However,

Efficacy Assessment of Montanide GEL 02 PR and Liposome‐Based Encapsulation as Adjuvants for an FrpA Subunit Vaccine Against Photobacteriosis in Solea senegalensis

Journal of Fish Diseases, EarlyView.
ABSTRACT Photobacteriosis is a major threat to marine aquaculture, and the siderophore transporter FrpA represents a promising target for effective subunit vaccine development. In this study, we evaluated Montanide GEL 02 PR and phosphatidylcholine‐based liposomes as aqueous and safer alternatives to Freund's adjuvant for an FrpA‐based subunit vaccine ...

Membrane Disintegration Caused by the Steroid Saponin Digitonin Is Related to the Presence of Cholesterol

Molecules, 2015
In the present investigation we studied the molecular mechanisms of the monodesmosidic saponin digitonin on natural and artificial membranes. We measured the hemolytic activity of digitonin on red blood cells (RBCs). Also different lipid membrane models (
