Carbon encapsulated magnetic nanoparticles for biomedical applications: thermal stability studies

Area of Science:

• Materials Science
• Nanotechnology
• Biomedical Engineering

Background:

• Carbon encapsulated magnetic nanoparticles (CEMPs) offer diverse biomedical applications.
• Their utility is dependent on the interaction between magnetic fields and biological systems.
• Understanding the thermal stability of CEMPs is crucial for their practical implementation.

Purpose of the Study:

• To investigate the thermal stability of CEMPs synthesized via radio frequency (RF) thermal plasma.
• To characterize the phase composition and morphology of the synthesized CEMPs.
• To determine the temperature threshold for the thermal degradation of the carbon nanostructures.

Main Methods:

• Synthesis of CEMPs using induction radio frequency (RF) thermal plasma.
• Characterization of phase composition using powder X-ray diffraction (XRD).
• Morphological analysis using High-Resolution Transmission Electron Microscopy (HRTEM).
• Thermal stability assessment via thermogravimetry (TGA) and differential thermal analysis (DTA).

Main Results:

• CEMPs were successfully synthesized using RF thermal plasma.
• Powder XRD and HRTEM provided insights into phase composition and morphology.
• Thermogravimetry and differential thermal analysis revealed that the carbon nanostructures are thermally stable up to 500 K.

Conclusions:

• The synthesized CEMPs exhibit significant thermal stability up to 500 K.
• This thermal robustness is a key prerequisite for their deployment in demanding biomedical environments.
• Further research can leverage these findings for developing advanced CEMP-based biomedical technologies.
