Preparation and characterization of magnetic chitosan particles for hyperthermia application

Pullulan acetate coated magnetite nanoparticles for hyper-thermia: Preparation, characterization and in vitro experiments

“…Magnetic nanoparticles with tailored surface chemistry have recently attracted a great deal of attention by virtue of their potential biomedical applications including magnetic resonance imaging (MRI) contrast enhancement [1][2][3][4], hyperthermia [5][6][7], immunoassay [8], and drug delivery [9]. Hyperthermia involves applying an alternating magnetic field of suitable frequency that produces heat dissipation through the oscillation of the internal magnetic moment of superparamagnetic particles.…”

Preparation of magnetic chitosan microspheres and its applications in wastewater treatment

“…Park et al [22] dispersed the barium ferrite into chitosan solutions with different weight ratios by ultrasonication, then the mixtures were added dropwise to NaOH aqueous solutions with syringe respectively, and the MCM with different components have been prepared. They found that the sizes of the microspheres increased with the content of chitosan increase.…”

“…In addition, the structure of chitosan chain was stiff, and chitosan could dissolve in very few solvents, usually only in acidic aqueous media. Based on these characteristics of chitosan, two methods for preparation of MCM have been summarized: reverse-phase suspension cross-linking method [17][18][19][20][21] , and precipitation method [22][23][24][25][26] .…”

Magnetic Nanoparticles: Synthesis, Surface Modifications and Application in Drug Delivery

“…Ferrite particles were prepared in a chitosan matrix at varying ratios (Park et al, 2005). The time period needed for reaching hyperthermia shortened upon increase of chitosan ratio while the saturation magnetization decreases.…”
