一般描述

Magnetic polystyrene particles
Superparamagnetic iron oxide nanoparticles embedded in polymer/polystyrene microspheres (magnetic beads) are useful for cell separation and labelling. It may also be useful in tissue repair, magnetic resonance imaging contrast enhancement, hyperthermia, immunoassay, detoxification of biological fluids, drug delivery.

应用

Micro particles based on polystyrene, magnetic has been used to deposit polyelectrolytes (PE), poly(allylamine hydrochloride), and poly(sodium 4-styrenesulfonate) (PAH/PSS) onto negatively charged magnetic polystyrene (PS) microparticles, to prepare PE-functionalized microparticles, for the fabrication of a biohybrid algal microswimmer toward biomedical applications.
