Title : Therapeutic and photodegradation applications PEG, PVA and PVP doped nanocomposites by hydrothermal method


Magnetic nanoparticles (NPs), are highly auspicious with distinct functional properties among the nanoparticles for biomedical applications. Among the magnetic nanoparticles, cobalt ferrite nanoparticles as well as its nanocomposites have been highly explored for myriad applications. This work involves the synthesis of cobalt ferrite capped with PEG, PVA and PVP by solvothermal method. Several characterizations techniques such as X-ray diffractometer (XRD), Scanning electron microscope (SEM), Fourier transform infrared spectroscopy (FTIR), Vibrating sample magnetometer (VSM) and diffused reflectance spectroscopy (DRS) were used to analyze the physico-chemical properties of the formulated samples. The crystallinity, morphological and the magnetic properties of the samples were influenced by PEG,PVA and PVP. The formulated nanoparticles showed enhanced antidiabetic, antioxidant and antimicrobial activities. The PVP doped sample gives the highest antifungi and antidiabetic activities, while PVA doped sample shows the highest antibacterial and antioxidant activities. The photodegradation of the sample was also enhanced against crystal violet with PVP doped sample having the highest efficiency. Hence, the introduction of polymers in the sample heighten the biomedical performance of the sample.
