Product Name
Name：Magnetic polystyrene nanosphere
Product Overview
Magnetic polystyrene nanospheres are a composite nanomaterial that combines the characteristics of magnetic nanoparticles and polystyrene polymers.
Magnetic Core: The core of magnetic polystyrene nanospheres is magnetic nanoparticles such as Fe3O4.
Polymer shell: The surface of the magnetic core is coated with polystyrene (PS), a synthetic polymer material, forming the shell of the nanospheres.
Technical Parameter
Magnetic particles are oleic acid modified iron oxide nanoparticles
Particle diameter: 80~140 nm
Saturation magnetization:~18 em2/g
Zeta potential: -30 mV
Iron tetroxide content: 60%
Main components: magnetic polystyrene nanospheres, ultrapure water
Product Features
Superparamagnetism: As the core is a magnetic material, magnetic polystyrene nanospheres can exhibit superparamagnetism under an external magnetic field, meaning they can rapidly magnetize and demagnetize.
Stability: Polystyrene shell can improve the stability and dispersibility of nanospheres in various media.
Surface functionalization: The surface of nanospheres can be further modified to enhance their stability or achieve specific biological functions, such as targeted drug delivery.
Biocompatibility: Polystyrene nanospheres typically have good biocompatibility and are suitable for applications in the biomedical field.
Application Fields
Biomedical: In the field of biomedical science, magnetic polystyrene nanospheres can be used for nucleic acid extraction, catalyst support, cell separation technology, resonance imaging, drug screening and targeting, disease detection and diagnosis, etc.
Catalyst carrier: Magnetic polystyrene nanospheres can be used as catalyst carriers, utilizing their magnetic properties for easy separation and recovery to improve the efficiency and lifespan of catalysts.
Magnetic adsorbent: Due to its excellent hydrophobicity and non biodegradability, magnetic polystyrene nanospheres can be used as magnetic adsorbents to remove pollutants in water treatment.
