Fe₃O₄ Nanoparticles (Co-precipitation Method)

Carboxy functionalized Fe₃O₄ nanoparticles have high negative surface charge, high magnetic properties, safe and environmentally friendly without pollution. They can be widely used in nanoprobe construction, magnetic resonance imaging and molecular imaging, drug carrier and targeted diagnosis and treatment integration research.

PEI functionalized Fe₃O₄ nanoparticles are brown clarified hydrocolloids, which have been filtered and sterilized by 0.22 um filter membrane.  They are easy to handle, easy to be phagocytosed by cells, and can be used for experimental studies of cellular transfection of DNA or RNA.

SiO₂ coated Fe₃O₄ nanoparticles have superparamagnetism, good water solubility, dispersibility, biocompatibility and stability. They can be used to construct targeted nanoprobes by surface modification of specific biomolecules such as antibodies.

Magnetic graphene consists of reduced graphene oxide loaded with magnetic Fe₃O₄ nanoparticles, which has magnetic responsiveness, catalytic properties, electrical and thermal conductivity. They can be used for magnetic separation, biocatalysis, treatment of environmental pollution, construction of nano drug carriers, and development of biosensing and detection methods.

Magnetic polystyrene nanospheres have a series of advantages, including but not limited to uniform particle size, smooth surface, large specific surface area and strong adsorption. They can be widely used in chromatography, microscopy, tissue separation technology, cancer therapy and DNA technology.

As a carrier of drugs, albumin has the advantages of stable chemical properties, non-toxicity, and non-antigenicity. It is easy to be distributed in tissues and can be concentrated in tumor sites. Albumin-modified magnetic nanoparticles have the characteristics of adjustable magnetic content, narrow size distribution and good biocompatibility. They can be used to construct magnetic drug carriers, construct magnetic resonance contrast agents, construct tumor magnetic induction hyperthermia carriers, and couple functional biomolecules such as antibodies.
