In this paper, magnetic hemostatic nanoparticles are shown for the first time to assist in minimally invasive treatment of internal bleeding, implying the introduction directly into the circulatory system followed by localization in the bleeding zone due to the application of an external magnetic field. (nature.com)
We also show here using a model blood vessel that the THR@ferria composite does not cause systematic thrombosis due to low activity, but being concentrated by an external magnetic field with simultaneous fibrinogen injection accelerates local hemostasis and stops the bleeding. (nature.com)
The particle-linked molecules can quickly agglomerate in the medium in response to a change in external magnetic field. (biomedcentral.com)

Adnano is a company that produces and sells iron oxide nanopowder for a variety of applications, including catalysis, biomedical imaging, magnetic storage, and environmental remediation. (adnanotech.com)
Adnano may target specific industries or applications that require iron oxide nanopowder, such as biomedical imaging or environmental remediation, and tailor their marketing messages accordingly. (adnanotech.com)
At the same time, the thickness of oxide film varies according to different environmental conditions during oxidation. (designerstudiostore.com)

Among the sensing technologies used, the one based on the Hall effect has played an important role owing to its ability to measure dc fields (i.e., constant in time), large frequency bandwidth, non-hysteretic behavior, operation at high magnetic fields, reliability, and low cost. (scirp.org)
Molecular dynamics simulations reveal semiconductivity-like behavior in coassemblies of positively charged nanoparticles and negatively charged small molecules. (weizmann.ac.il)

For this purpose, magnetic nanoparticles (Fe 3 O 4 ) are generally utilized to fabricate nanocomposite with LDH. (hindawi.com)
In this work, the solid-in-oil-in-water (S/O/W) emulsion-solvent extraction/evaporation method was utilized to fabricate magnetic polymer microspheres incorporating SPIONs in PHBV. (nature.com)

This was also proven via magnetic susceptibility measurement as a higher value of this magnetic property was detected for PHBV/SPIONs Lauric microspheres. (nature.com)
It was revealed that the magnetic PHBV microspheres were non-toxic when assessed with mouse embryotic fibroblast cells (MEF) at different concentrations of microspheres. (nature.com)
