Zinc oxide nanoparticles as selective killers of proliferating cells [PDF]

, 2011
Background: It has recently been demonstrated that zinc oxide nanoparticles (ZnO NPs) induce death of cancerous cells whilst having no cytotoxic effect on normal cells.

Development and use of iron oxide nanoparticles (Part 1): Synthesis of iron oxide nanoparticles for MRI [PDF]

Biomedical Imaging and Intervention Journal, 2010
Contrast agents, such as iron oxide, enhance MR images by altering the relaxation times of tissues in which the agent is present. They can also be used to label targeted molecular imaging probes. Unfortunately, no molecular imaging probe is currently available on the clinical MRI market.

Vacancy Coalescence during Oxidation of Iron Nanoparticles [PDF]

Journal of the American Chemical Society, 2007
In the present work, we analyze the geometry and composition of the nanostructures obtained from the oxidation of iron nanoparticles. The initial oxidation of iron takes place by outward diffusion of cations through the growing oxide shell. This net material flow is balanced by an opposite flow of vacancies, which coalesce at the metal/oxide interface.

The Influence of Catechols on the Magnetization of Iron Oxide Nanoparticles

Nanomaterials, 2023
In this study, MNPs were functionalized with pyrocatechol (CAT), pyrogallol (GAL), caffeic acid (CAF), and nitrodopamine (NDA) at pH 8 and pH 11. The functionalization of the MNPs was successful, except in the case of NDA at pH 11. The thermogravimetric analyses indicated that the surface concentration of the catechols was between 1.5 and 3.6 molecules/

Superparamagnetic Iron Oxide Nanoparticles [PDF]

Current Directions in Biomedical Engineering, 2019
Abstract The direct detection of the spatial distribution of Superparamagnetic Iron Oxide Nanoparticles (SPIONs) as a tracer for Magnetic Particle Imaging (MPI) enables threedimensional functional images with high spatial and temporal resolution. The commercially available tracers have not been developed primarily for MPI.

The Detailed Bactericidal Process of Ferric Oxide Nanoparticles on E. coli

Molecules, 2018
While nanoparticles exert bactericidal effects through the generation of reactive oxygen species (ROS), the processes of the internalization of and the direct physical damage caused by iron oxide nanoparticles are not completely clear.
