The aggregation and colloidal stability of three, commercially-available, gamma-aluminum oxide nanoparticles (γ-Al₂O₃ NPs) (nominally 5, 10, and 20-30 nm) were systematically examined as a function of pH, ionic strength, humic acid (HA) or clay minerals (e.g., montmorillonite) concentration using dynamic light scattering and transmission electron microscopy techniques. NPs possess pH-dependent ...

BACKGROUND Non-eosinophilic nasal polyps (NPs) show less inflammatory changes and are less commonly associated with lower airway inflammatory disorders such as asthma, compared with eosinophilic NPs. However, the development of non-eosinophilic NPs which is a predominant subtype in Asian population still remains unclear. METHODS A total of 81 patients (45 with non-eosinophilic NPs and 36 with...

recent progress in nanotechnology and electrochemical methods can be applied to fine control of the size, crystal structure, and surface properties of iron oxide nanoparticles. here we appliedcathodic electrochemical deposition (ced) as an efficient and effective tactic for synthesisand double coating of surface of superparamagnetic iron oxide nanoparticles (spions). in first step, bare fe3o4 n...

Objective(s): A new strategy in recent studies is using effective tuberculosis (TB) subunit vaccines combined with appropriate carriers and adjuvants which have shown promising results in preclinical and clinical studies. The aim of the present study was to evaluate the PLGA:DDA hybrid nanoparticles (NPs) for subcutaneous delivery of a novel multistage subunit vaccine ...

magnetic nanoparticles are the good choice for using in mri as the contrast agent. iron oxide particles such as magnetite (fe3o4) or its oxidized form maghemite (γ-fe2o3) are the most commonly employed in biomedical applications. in this study, we synthesized and optimized the preparation of chitosan manganese-ferrite nanoparticles (cmn-fe nps) and evaluated its ability for the mice macrophage ...

We present a microfluidic platform that allows undergoing different chemical operations in a nanoliter droplet starting from the colloidal suspension of magnetic iron oxide (γ-Fe2O3) nanoparticles "NPs" (ferrofluid). These operations include: mixing, flocculation, magnetic decantation, colloidal redispersion, washing, surface functionalization, heating and colloidal assembly. To prove the platf...

Numerous studies have demonstrated that damage of kidney of mice can be caused by exposure to titanium dioxide nanoparticles (TiO(2) NPs). However, the molecular mechanism of TiO(2) NPs-induced nephric injury remains unclear. In this study, the mechanism of nephric injury in mice induced by an intragastric administration of TiO(2) NPs was investigated. The results showed that TiO(2) NPs were ac...
