UnknownGraphene Oxide/ZnS:Mn Nanocomposite Functionalized with Folic Acid as a Nontoxic and Effective Theranostic Platform for Breast Cancer Treatment.
Nanoparticle-based cancer theranostic agents generally suffer of poor dispersability in biological media, re-agglomeration over time, and toxicity concerns. To address these challenges, we developed a nanocomposite consisting of chemically-reduced graphene oxide combined with manganese-doped zinc su...

UnknownControlling the transverse proton relaxivity of magnetic graphene oxide.
The engineering of materials with controlled magnetic properties by means other than a magnetic field is of great interest in nanotechnology. In this study, we report engineered magnetic graphene oxide (MGO) in the nanocomposite form of iron oxide nanoparticles (IO)-graphene oxide (GO) with tunable ...

UnknownT1- and T2-weighted Magnetic Resonance Dual Contrast by Single Core Truncated Cubic Iron Oxide Nanoparticles with Abrupt Cellular Internalization and Immune Evasion.
Conventional T1- or T2-weighted single mode contrast-enhanced magnetic resonance imaging (MRI) may produce false results. Thereby, there is a need to develop dual contrast agents, T1- and T2-weighted, for more accurate MRI imaging. The dual contrast agents...

UnknownMorphology Effect of PEGylated Iron Oxide Nanoparticles on the Enhancement of MRI Contrast Signal in Breast Cancer.
MRI is one of the most powerful imaging modalities to diagnose cancer at early stages, which can be further improved with contrast agents (CAs). For this purpose, iron oxide nanoparticles (IONs) are commonly used as T2 probes to enhance the contrast in MRI scans. The morphology of ...

UnknownGeometry and Surface Area Optimization in Iron Oxide Nanoparticles for Enhanced Magnetic Properties.
Iron oxide nanoparticles (IONPs) are recognized for their potential in biomedical applications due to their distinctive physicochemical properties. This study investigates the synthesis of IONPs with various geometric morphologies-cubic, star-like, truncated icosahedron, and spherical-via thermal de...

UnknownMagnetic Control of the Manganese Photoluminescence in Fe3O4/l-Cys ZnS:Mn Nanocomposites.
We investigated the magnetic control of the Mn photoluminescence (PL) in iron oxide/l-cysteine-capped zinc sulfide (Fe3O4/l-cys ZnS:Mn) nanocomposites via temperature- and field-dependent PL intensity studies. Fe3O4/l-cys ZnS:Mn was synthesized following a...
