Design and Development of Fe3O4@Prussian Blue Nanocomposite: Potential Application in the Detoxification of Bilirubin.

BACKGROUND

Prussian blue nanoparticles (PBNPs) due to their high solubility, stability, flexible molecular structure, tunable size, easy synthesis, and surface modification have attracted the attention of researchers as high-efficiency therapeutic agents. Recently, it has been reported that magnetic nanoparticles can be to bind pathogenic substances on their surface, followed by a recollection by magnetic separation. Considering the potential application of PB and magnetic nanoparticles, in the current study we aimed to strategically design and synthesize a highly efficient nano-magnetic bilirubin scavenger system based on iron oxides@prussian blue nanocomposites (Fe3O4@PB) NCs.

MATERIALS AND METHODS

The Fe3O4@PB NCs were synthesized by an improved shell-growing procedure and identified using advanced characteristic techniques TEM, SEM, XRD, DLS, and Zeta potential. Synthesized Fe3O4@PB NCs showed good magneton properties and also demonstrated dramatic absorbent properties that empower use as an eco-friendly adsorbent nano agent for the detoxification of toxins. In addition, Fe3O4@PB nanoparticles showed high performance of bilirubin absorption in the serum and blood of sickle cell anemia patients. (Temp. 37.7 ºC, the dose of adsorbent: 1 mg/mL, incubation time 30 min, and initial concentration: 0.25 mg/mL).

RESULTS

The results demonstrated an ideal adsorption capacity (86%) of Fe3O4@PB NCs which is significant compared to the reported adsorbents agents. These results pave the way for the application of Fe3O4@PB NCs for the effective purification of toxins from patients' body fluids.
