Stable Room-Temperature Magnetic Carbon/Graphite: From Discovery to Bionanotechnological Applications
Year: 2022
Type: article
Abstract: Almost two decades ago, we reported -and patented -by the first time on a simple chemical route aiming to synthetize stable room-temperature magnetic bulk carbon/graphite.We obtained the experimental confirmation that its magnetism originates from defects in the structure (and not from ferromagnetic impurities) from direct measurement of the local magnetic field using 13 C nuclear magnetic resonance associated to the numerical results obtained from DFT (Density-Functional theory) calculations.We have also developed the chemical synthesis route to obtain nanofluid magnetic carbon/graphite.In this short review of our own work, we briefly show these findings as well as the main physical and chemical properties of this material and recent results aiming biotechnological and medical applications.From theoretical calculation, we have analyzed its possible use as a contrast, for example, in the MPI (Magnetic Particle Imaging) technique.Finally, we show here the potential of this material to be used as a drug carrier to reach different targets like those associated with cancer, diabetes and Alzheimer by using what we have called MAGUS ® (Magnetic Graphite Universal System).
