ROS‐Responsive Nanobubbles for Dual‐Enhanced Ultrasound and Magnetic Resonance Imaging of Tumor Oxidative Stress

Advanced Science, EarlyView.
We report the development of biotinylated PEGylated bilirubin‐coated perfluoropentane (bt‐PEG‐BR@PFP) nanobubbles, a novel class of ROS‐activatable and dual‐modality contrast agents that amplify both ultrasound (US) and magnetic resonance imaging (MRI) signals in response to elevated ROS.

Materials‐Guided Gene‐Ionizable Lipid Nanoparticles to Reverse Iron‐Associated Immune Resistance in Renal Cancer

Advanced Science, EarlyView.
ABSTRACT Iron overload is a common metabolic disturbance in cancer and contributes to poor outcomes in renal cell carcinoma (RCC), yet its effects on the tumour immune microenvironment remain unclear. Here we identify a previously unrecognized immunosuppressive axis in which iron overload downregulates the palmitoyltransferase ZDHHC12 in CD8+ T cells ...

Zeta Potential Measurement

2010
This chapter describes a method for the measurement of the electrostatic potential at the electrical double layer surrounding a nanoparticle in solution. This is referred to as the zeta potential. Nanoparticles with a zeta potential between -10 and +10 mV are considered approximately neutral, while nanoparticles with zeta potentials of greater than +30

The zeta-potential of cement

Cement and Concrete Research, 1985
Abstract Zeta-potential measurements provide new informations on cement hydration, gel structure formation and the effects of chemical admixtures. The formation and significance of a zeta-potential of cement in aqueous suspension is discussed with respect to the hydration of cement and some new data on the zeta-potential of cement and fly ash under ...

Zeta potential of phosphors

Colloids and Surfaces A: Physicochemical and Engineering Aspects, 1995
Abstract The zeta potentials of several oxide, sulfide, and oxysulfide phosphors were measured in isopropyl alcohol (IPA) and IPA containing dissolved nitrate salts and water. The zeta potentials of phosphors in IPA without dissolved salts are negative.

Zeta Potential in the Development of Pharmaceutical Suspensions

Journal of Pharmaceutical Sciences, 1966
A discussion of a microelectrophoretic mobility apparatus (Zeta-Meter) is presented in connection with some prerequisite studies with a model dispersed system. The limitations of the fundamental Helmholtz-Smoluchowski formula for calculating zeta potential as it applies to a study of real pharmaceutical systems is presented.

Zeta Potential Determination of Targeted Nanoparticles

2021
Abstract In a dispersion system, colloids interact with one another. It is assumed that these interactions are promoted by two main forces, London-van der Waals forces that lead to attraction and electromagnetic effects that leads to repulsion. The zeta potential (ZP) is the electrical potential at the surface of a hydrodynamic shear plane.
