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

Study of Hydrophobic Domains in Humic Acids [PDF]

, 2008
Fyzikálně-chemická povaha hydrofobních domén huminových kyselin byla studována z několika hledisek. K objasnění významu fluorescenčních spekter byly vzorky podrobeny sekvenční frakcionaci, která pomohla k částečnému objasnění vlivu vodorozpustných složek,

Supramolecular perspectives in colloid science [PDF]

, 2008
Supramolecular chemistry puts emphasis on molecular assemblies held together by non-covalent bonds. As such, it is very close in spirit to colloid science which also focuses on objects which are small, but beyond the molecular scale, and for which other ...

Bio‐Based Amphiphilic Farnesyl Glycidyl Ether Block Copolymers: Aqueous Self‐Assembly and Solubilization Boosting

Chemistry – A European Journal, EarlyView.
Bio‐derived amphiphilic poly(ethylene glycol)‐b‐poly(terpenyl glycidyl ether) diblock copolymers (mPEG114‐b‐PTGEm) were synthesized via AROP from farnesyl glycidyl ether (FarGE) and its hexahydrogenated derivative (HHFarGE). Block copolymer amphiphilicity is easily tunable via the TGE block size m and systematically affects the critical micelle ...

Micellization and surface properties of Triton X 100 in aqueous solution of short-chain alcohols

Results in Chemistry
This study investigates the micellization and surface properties of nonionic surfactant Triton X-100 (TX100) in binary water-alcohol mixtures containing methanol (MeOH), ethanol (EtOH), and 1-propanol (1-PrOH) at 293.15 K.

Dynamics of Vesicle Formation from Lipid Droplet: Mechanism and Controllability

, 2009
A coarse-grained model developed by Marrink et al. [J. Phys. Chem. B 111, 7812 (2007)] is applied to investigate vesiculation of lipid [dipalmitoylphosphatidylcholine (DPPC)] droplets in water.

Sulfonium‐Based Antimicrobial Block Copolymers: Influence of Hydrophobicity on Biological Activity and Antibiotic Synergy

Macromolecular Rapid Communications, EarlyView.
Sulfonium‐based antimicrobial block copolymers combine an active cationic hydrophobic block with a neutral hydrophilic block to improve cytocompatibility. The hydrophobicity of the sulfonium‐based block controls the activity against S. aureus and E coli.

Adsorption Properties and Wettability of Ethoxy- and Propoxy- Derivatives of 2-Ethylhexanol as Sterically Specific Surfactant Structures

Molecules
2-ethylhexanol, an oxo alcohol competitively priced on the global market, has not been explored intensively as a raw material for surfactants, due to its weak hydrophobic character.

N‐Geranylated Amino Acid Surfactants with Low Critical Micelle Concentrations from Abundant, Naturally Derived Starting Materials

ChemistryOpen, EarlyView.
Cleaning Up Surfactants: Realising critical micelle concentrations lower than sodium dodecyl sulfate with sustainable surfactants prepared from amino acids and naturally occurring aldehydes. In this work, a simple method for the preparation of N‐alkylated amino acid surfactants in 1–2 steps is reported.
