We perform multiple particle tracking (MPT) on a thermally-gelling oil-in-water nanoemulsion system. Carboxylated and plain polystyrene probes are used to investigate the role of colloidal probe size and surface chemistry on MPT in the nanoemulsion system. As temperature increases, hydrophobic groups of PEG-based gelators (PEGDA) partition into the oil/water interface and bridge droplets. This ...

the aim of this investigation was to design and develop nanoemulsions as novel delivery systems for rapamycin. phase behavior of quaternary systems composed of traicetin (as oil), various surfactants and co-surfactants and water at different surfactant/co-surfactant weight ratios were investigated by the construction of phase diagrams. formulations were taken from the o/w ne region of the phase...

Nanoemulsions possess powerful nano-scale properties that make them attractive for diverse applications such as drug delivery, food supplements, nanoparticle synthesis and pharmaceutical formulation. However, there is little knowledge in nanoemulsion literature about controlling and predicting droplet size. In this article, we propose a scaling relation to predict the dependence of nanoemulsion...

A dispersed nano-system with droplet sizes as small submicrons is called a nanoemulsion. Nanoemulsions are thermodynamically stable, transparent, isotropic liquid mixtures of oil, water, surfactant, and co-surfactant. Nanoemulsion typically has between 20 200 nanometer. The size composition the scattered particles in continuous phase primary distinctions an emulsion This approach intended to al...

Nanoemulsions are submicron sized emulsion that is under extensive investigation as drug carriers for improving the delivery of therapeutic agents. These are by far the most advanced nanoparticle systems for the systemic delivery of active pharmaceutical for controlled drug delivery and targeting. These are the thermodynamically stable isotropic system in which two immiscible liquid (water and ...

Nickel microspheres were synthesized via a water-in-oil reverse nanoemulsion system using nickel nitrate as the nickel precursor and hydrazine hydrate as the reducing agent. The nanoemulsion was a triton X-100/cyclohexane/water ternary system. The surface morphology of the nickel microspheres was studied by scanning electron microscopy, which indicated that the microspheres had a nanoporous str...

Solid lipid nanoparticles (SLN), nanostructured lipid carriers (NLC) and nanoemulsion (NE) of lornoxicam (LRX) were prepared for the treatment of painful and inflammatory conditions of the skin. Compritol® 888 ATO, Lanette® O and oleic acid were used as solid and liquid lipids. SLN, NLC and NE were found physically stable at various temperatures for 6 months. Case I diffusional drug release was...

in this study formation and properties of o/w emulsion stabilized by a mixture of sodium caseinate (2, 5 and 10 wt %) and non-ionic emulsifier tween 80, sorbitan mono-9-octadecenoate, (0, 0.5, 1 and 1.5 wt %) were investigated at various ph values(3, 5 and 7) and calcium ion concentrations (0, 0.2, 0.4 and 0.6 wt%). emulsion samples were prepared by using a sonicator with a nominal power output...

background and objectives: recently, due to the interest of healthy lifestyle demand for research on novel methods of increasing the shelf-life of food products without the necessity of using preservatives has extended rapidly in the world. ability of nanoemulsions to improve global food quality has attracted great attention in food preservation. this is as a result of a number of attributes pe...
