Effect of folic acid decorated magnetic fluorescent nanoparticles on the sedimentation of starch molecules

Abstract

Ferrite–folic acid (FA) nanohybrids were synthesized and characterized by various analytical tools like Fourier transform infrared spectroscopy, UV–Visible spectroscopy, fluorescence spectroscopy, field emission scanning electron microscopy, X-ray diffraction analysis and vibrating sample measurement techniques. After the nanohybrid formation, both the crystallinity and the magnetization values of ferrite were disturbed due to the surface functionalization of ferrite by FA. The role of nanohybrid on the structure–property relationship of starch, particularly the sedimentation of starch under three different pHs, was evaluated. Again the magnetization value of Fe3O4–FA/starch nanocomposite system was reduced due to the encapsulation effect. The sedimentation velocity of starch under the influence of nanohybrid was enhanced in the acidic medium.
