Correction: Carboxymethyl-sagocellulose-stabilized Fe3O4 nanoparticles with 5-fuorouracil as photothermal agents for tumor ablation

There is a continuous growth of interest in the development of nano-drug delivery systems that could combine therapy and diagnosis of cancer. Novel multifunctional superparamagnetic iron oxide nanoparticles (SPIONs, chemically Fe3O4) conjugated with carboxymethyl sagocellulose (CMSC), and 5-fluorouracil (Fe3O4-CMSC-5FU) were synthesized. The conjugated nanoparticles have the magnetic properties of the SPIONs, which allows the nanoparticles to be localized at the target area by applying an external magnetic field. SPIONs generate heat upon exposure to laser lights, resulting in a photothermic effect. The drug-loading efficiency of 5-FU into the SPIONs-CMSC conjugated nanoparticles was 70 to 84
