Metal‐Ligand Complexes as Multifunctional Platforms for Photo‐Activated Cancer Therapy

Advanced Science, EarlyView.
Metal‐ligand complexes serve as multifunctional platforms for photo‐activated cancer therapy, facilitating photothermal and photodynamic effects through light absorption and reactive oxygen species generation. This review categorizes these complexes by ligand and metal types, examines their roles in combined therapeutic approaches, and explores ...

Effect of percentage of methanol on micellization position of mixed surfactant interaction in the absence and presence of dye

Results in Chemistry
The interaction behavior of mixed surfactant-dye systems, i.e., anionic surfactant sodium dodecyl sulfate (SDS), cationic surfactant cetyl pyridinium chloride (CPC), and dye methyl orange (MO) was investigated through the allocation of micelles using ...

Single‐component cationic polyethylenimine thermogel for sustained and localized gene delivery to combat multi‐drug resistant cancer

BMEMat, EarlyView.
A cationic thermogelling copolymer employing branched PEI‐25 kDa as the sole hydrophilic segment can be facilely complexed with plasmid by physical mixing in the sol phase. Spontaneous gelation is achieved via self‐assembly after injection due to physiological temperature. Sustained and localized release of plasmid from the cationic PEI‐thermogel leads

Interaction of Caffeic Acid with SDS Micellar Aggregates

Molecules, 2019
Micellar systems consisting of a surfactant and an additive such as an organic salt or an acid usually self-organize as a series of worm-like micelles that ultimately form a micellar network.

Rhamnolipid Self‐Aggregation in Water–Bioglycerol Mixtures: Byproduct Valorization for Sustainable Formulation Design

ChemPlusChem, EarlyView.
Bioglycerol, the primary byproduct of biodiesel production, has the potential to be valorized as a cosolvent in industrial formulations. Surface tension and self‐diffusion data reveal that rhamnolipid self‐aggregation in water is poorly affected by the addition of bioglycerol up to very high concentrations. These results demonstrate that biosurfactants

Micellization Thermodynamics of Pluronic P123 (EO20PO70EO20) Amphiphilic Block Copolymer in Aqueous Ethylammonium Nitrate (EAN) Solutions

Polymers, 2017
Poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide) (PEO-PPO-PEO) block copolymers (commercially available as Pluronics or Poloxamers) can self-assemble into various nanostructures in water and its mixtures with polar organic solvents ...

Quantifying the Influence of Poly(Ethylene glycol) on the Micelle Formation of Nonionic Detergents

ChemPlusChem, EarlyView.
The influence of poly(ethylene glycols) (PEG) with different molecular weights on the critical micelle concentration of nonionic detergents is quantified based on fluorescence spectra of 8‐anilinonaphthalene‐1‐sulfonate (ANS) and found to depend on the concentration of oxyethylene (OE) units rather than polymer length.
