Synthesis , Characterization and applications of Gentamicin functionalized Fe 3 O 4 nano hybrid

Recently the applications of functionalized magnetic nano particles are increased in a linear fashion. This is due to the ease of synthesis and controlled growth of magnetic nano particles. In the present investigation gentamicin drug functionalized Fe3O4 nanoparticles were synthesized by co-precipitation method. Thus obtained nano hybrid was characterized by Fourier transform infrared (FTIR) spectroscopy, UV-visible spectroscopy, X-ray diffractogram (XRD), Field emission scanning electron microscopy (FE-SEM), and Vibrating sample magnetometer (VSM) like methods. The above synthesized nano hybrid is sensitive to magnetic force and gravitational force. This principle is used here to increase the settling rate of starch under three different pHs namely acid (pH-3.5), alkaline (pH-12.5) and neutral (pH-7.1). It was found that while increasing the percentage loading of nano hybrid the sediment height of starch is smoothly increased. The VSM value of starch is smoothly increased. The VSM value of the starch/Fe3O4gentamicin nano composites were reduced due to the encapsulation effect. Thus obtained nano composites were characterized by FTIR, DSC, TGA and SEM. The settling velocity of starch under three different pHs were calculated and critically compared. KeywordsStarch, Functionalization, Gentamicin, Sedimentation, nano hybrid.
