Characterization of magnetic nanoparticle by dynamic light scattering

Characterization of magnetic nanoparticle by dynamic light scattering

Here we provide a complete review on the use of dynamic light scattering (DLS) to study the size distribution and colloidal stability of magnetic nanoparticles (MNPs). The mathematical analysis involved in obtaining size information from the correlation function and the calculation of Z-average are introduced. Contributions from various variables, such as surface coating, size differences, and ...

Characterization of whey protein-polyphenol interactions by dynamic light scattering

Many drinkable dairy products added with green tea polyphenols have been launched by food industries because epidemiological studies suggest an association between the prevention of diseases and the consumption of polyphenol-rich beverages or foods. However, polyphenols have a significant affinity for proteins that leads to formation of soluble complexes, which can grow in size and even form se...

Entrapment–D-(+)-Glucose Water Nanodroplet: Synthesis and Dynamic Light Scattering

In the present research, the D-(+)-Glucose–confined water nanodroplets with mean size in the range of 6-11 nm were synthesized at D-(+)-Glucose different concentrations by AOT reverse micelles (RMs) method as a function of mass fraction of droplet (MFD) at the constant water-to-surfactant molar ratio ( W=40). The dynamic light scattering of the nano-sized water droplets containing the D-(+)-Glu...

Hydrodynamic Characterization by Analytical Ultracentrifugation and Dynamic Light Scattering

A laboratory-made sample of the polysaccharide xylinan (acetan) has been further characterized with respect to ( i ) purity, (ii) molar mass and polydispersity, and (iii) gross conformation by a combination of hydrodynamic measurements (sedimentation velocity and equilibrium analytical ultracentrifugation, viscometry, and dynamic light scattering) in aqueous NaCl (I = 0.10 mol. L-'). Sedimentat...
