In situ tailoring of carbon dots-metal ferrite nanohybrid as multipurpose marker agent of HeLa cancer cells

The development of multifunction material was considered to attain effectiveness on cancer treatment. The present study pursues the potential application of metal ferrite nanoparticles covered with CDs to get dual-active nanomaterial on fluorescent and magnetic responses that were prepared on a one-pot solvothermal method. Some analyses indicated the nanohybrids consisted of amorphous structure. Besides, the optical analysis performed optimum emission with QY percentage up to 0.9 and 0.6, respectively. Magnetic response assessment confirmed CDs@MnFe₂O₄-15 has good superparamagnetic properties with saturation magnetization value of 38.485 emu/g, while CDs@CuFe₂O₄-15 at 9.5245 emu/g. The DLS measurement showed an average size of CDs@MnFe₂O₄-45 at 63.98 nm, while CDs@CuFe₂O₄-45 at 55.46 nm. Then, this nanosized drive to perform good photoluminescent properties and good cytotoxicity due to the nanohybrids of CDs@MFe₂O₄-45 can easily enter the HeLa cells without harming its original structure. The above finding has well-proven good clinical potency of the nanohybrid as simultaneous fluorescent and magnetic-based detection. Graphical abstract: [Figure not available: see fulltext.]
