Abstract Dynamic light scattering (DLS) is an essential technique for nanoparticle size analysis and has been employed extensively decades, but despite its long history popularity, the choice of weighting mean distribution often appears to be picked ad hoc bring results into agreement with other methods expectations by any means necessary . Here, we critically discuss application DLS characteri...

Background Intravenous drug delivery is an advantageous choice for rapid administration, immediate drug effect, and avoidance of first-pass metabolism in oral drug delivery. In this study, the synthesis, formulation, and characterization of atorvastatin-loaded polyurethane (PU) nanoparticles were investigated for intravenous route of administration. Methods First, PU was synthesized and chara...

metal—polyaniline nanocomposites such as platinum-polyaniline nanocomposite is prepared by insitu oxidative polymerization of aniline and reduction of pt+4 ions into pt nanoparticles. thepolymerization of aniline was carried out in the presence of 1(2ptcn6 [potassium hexa cyanoplatinate (iv)] as oxidizing agent. during the reaction aniline monomers undergo oxidation andform polyaniline (pant) w...

The absolute coagulation rate constants of monodisperse spherical colloids in aqueous suspension were measured at the early stage of the coagulation processes by using two different techniques: single particle light scattering (SPLS) and simultaneous static and dynamic light scattering (SLS + DLS). Single particle light scattering determines the cluster-size distribution directly by counting th...

Chitooligosaccharides with degree of polymerization from 5 to 15 have been modified different lipophilic chains, fatty epoxide acids. Their interfacial properties such as critical micellar concentrations, rheology and tension were studied establish structure-properties relationships. ability self-assemble well their shape assessed by light scattering (dynamic static) transmission electron micro...

Three Monte Carlo programs were developed which keep track of the status of polarization of light traveling through mono-disperse solutions of micro-spheres. These programs were described in detail in our previous article [1]. This paper illustrates a series of Monte Carlo simulations that model common experiments of light transmission and reflection of scattering media. Furthermore the codes w...
