Abstract:In this work, the aggregation of nanoparticles in an aqueous colloidal solution of magnetite, stabilized by creating a citrate shell on the particle surface is studied. Electron microscopy and laser correlation spectroscopy were used as experimental methods. Optical measurements were carried out both at zero external magnetic field and in the fields differently oriented relative to the probing laser beam. It is shown that the samples tend to form large aggregates even without the application of the field, and … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
