Exploring a green and precise approach based on graphene oxide-cobalt ferrite nanocomposite for detection and quantification of vitamin B9 and antibacterial assessment

Structure and morphology of the as-synthesized samples

The FT-IR spectra of synthesized compounds is shown in Fig. 1a. The peaks reported at 3374.33 cm⁻¹ for GO, 3426.40 cm⁻¹ for CoFe₂O₄ and 3354.09 cm⁻¹ for CoFe₂O₄/GO are all related to…
