Effect of Temperature and Alcohol on the Determination of Critical Micelle Concentration of Non- Ionic Surfactants in Magnetic Water

مجلة بغداد للعلوم, 2020
The determination of critical micelle concentration of selected non-ionic surfactants (Tween 20,40 and 80) have been investigated using magnetic water(MW)as an aqueous medium.Conductometry technique is used to determine critical micelle concentration.The

Critical self-association of bile lipids studied by infrared spectroscopy and viscometry.

Journal of Lipid Research, 1990
Fourier transform infrared (FTIR)-attenuated total reflection (ATR) spectroscopy and viscometry were applied to study the micellization of two bile lipids, sodium taurochenodeoxycholate (NaTCDC) and sodium glycocholate (NaGC), in aqueous solutions.

Influence of lipid chain unsaturation on melittin-induced micellization [PDF]

, 1996
It is well known that melittin, an amphipathic helical peptide, causes the micellization of phosphatidylcholine vesicles. In the present work, we conclude that the extent of micellization is dependent on the level of unsaturation of the lipid acyl chains.

Study on the Effects of Biologically Active Amino Acids on the Micellization of Anionic Surfactant Sodium Dodecyl Sulfate (SDS) at Different Temperatures

Chemistry, 2022
The micellar properties of the anionic surfactant, sodium dodecyl sulfate (SDS) are modified by the biologically active amino acids. Amino acids (AAs) have experienced a variety of interactions and are proposed to influence SDS micelles due to their ...

Photo-Induced Micellization of Block Copolymers

, 2010
We found novel photo-induced micellizations through photolysis, photoelectron transfer, and photo-Claisen rearrangement. The photolysis-induced micellization was attained using poly(4-tert-butoxystyrene)-block-polystyrene diblock copolymer (PBSt-b-PSt ...

Quantitative Visualization of Intracellular Nanometabolism Using Peak‐Shifted Dual‐State Emissive FRET Nanoprobes

Advanced Science, EarlyView.
This study reveals the long‐elusive intracellular dissolution mechanism of carrier‐free nanomedicines. By utilizing peak‐shifted dual‐state emissive FRET nanoprobes (PDFNPs) that undergo a distinct ratiometric fluorescence peak shift upon disassembly, we achieve real‐time, quantitative tracking of dissolution kinetics in live cells.

Characterization of biosurfactants’ micelles formation using fluorescence measurements: sodium taurocholate as case of study

ADMET and DMPK
Background and purpose: The evaluation of micellization parameters of surfactants that aggregate gradually, such as bile salts, is not trivial. In this work, different probes and data treatment models are tested to set up an analytical method based on ...
