Interaction of anionic surfactant with polymeric nanoparticles of similar charge.
Summary of "Interaction of anionic surfactant with polymeric nanoparticles of similar charge."
The formation of micelle-like nanosize aggregates above a critical aggregation concentration (CAC) by a water-soluble, amphiphilic, and statistical copolymer poly(SAMPS/DA) of sodium N-acrylamidomethylpropanesulfonate (SAMPS) and N-dodecylacrylamide (DA) was studied. The structural changes that result from the interactions between the polymeric nanoparticles and sodium dodecylsulfate (SDS), an anionic surfactant, were studied with the aid of surface tension, viscosity, steady-state fluorescence, dynamic light scattering, and transmission electron microscopic techniques. In dilute solution with polymer concentration C(p)

Medical and Biotech [MESH] Definitions
Holothurin
A highly toxic saponin occurring in HOLOTHUROIDEA. This marine toxin is an anionic surfactant, hemolyzing ERYTHROCYTES.
Nanoparticles
Nanometer-sized particles that are nanoscale in three dimensions. They include nanocrystaline materials; NANOCAPSULES; METAL NANOPARTICLES; DENDRIMERS, and QUANTUM DOTS. The uses of nanoparticles include DRUG DELIVERY SYSTEMS and cancer targeting and imaging.
Magnetite Nanoparticles
Synthesized magnetic particles under 100 nanometers possessing many biomedical applications including DRUG DELIVERY SYSTEMS and CONTRAST AGENTS. The particles are usually coated with a variety of polymeric compounds.
Ions
An atom or group of atoms that have a positive or negative electric charge due to a gain (negative charge) or loss (positive charge) of one or more electrons. Atoms with a positive charge are known as CATIONS; those with a negative charge are ANIONS.
Sodium Dodecyl Sulfate
An anionic surfactant, usually a mixture of sodium alkyl sulfates, mainly the lauryl; lowers surface tension of aqueous solutions; used as fat emulsifier, wetting agent, detergent in cosmetics, pharmaceuticals and toothpastes; also as research tool in protein biochemistry.
