Synthesis of monodisperse magnetite nanoparticles via chitosan–poly(acrylic acid) template and their application in MRI

Preparation and inductive heating property of Fe3O4–chitosan composite nanoparticles in an AC magnetic field for localized hyperthermia

“…Li et al [36] fabricated the chitosan-Fe 3 O 4 nanocomposite particles by the covalent binding of chitosan onto the surface of magnetic Fe 3 O 4 nanoparticles. Feng et al [47] synthesized monodisperse Fe 3 O 4 nanoparticles by using a chitosan-polyacrylic acid template and found that the Fe 3 O 4 nanoparticles had a significant magnetic resonance signal enhancement in T2-weighted image of lymph nodes. Lee et al [48] developed a novel MRI-detectable embolic microspheres composed of superparamagnetic Fe 3 O 4 nanoparticles and chitosan.…”

Synthesis, Surface Modification and Characterisation of Nanoparticles

“…Moreover, the polymer plays a role of size controlling and aggregation preventing of inorganic nanoparticles. In our research, ultrasmall magnetite nanoparticles were prepared using chitosan-polyacrylic acid (CS-PAA) nanospheres as template [23]. The CS-PAA hollow nanospheres could be prepared by polymerization of acrylic acid monomers in the presence of chitosan.…”

Effect of Process Parameters on Properties of Colloids in a Continuous‐Flow Microreactor System

“…Hydrothermal method [22], coprecipitation [23], sonochemical method [24][25][26], flame spray pyrolysis [27,28], solution spray method [29], solvothermal process [30], microwave-assisted method [31], and aerosol routes [32] were practiced for synthesis of hematite, maghemite, and wustite forms of iron oxide nanoparticles [33]. Feng et al [34] used chitosanpolyacrylic acid to produce monodisperse iron oxide nanoparticles by coprecipitation in a batch process. Martinez-Mera et al [35] synthesized iron oxide nanoparticles by a colloidal reduction route at room temperature without surfactant in the range of 4-43 nm.…”
