The present study was made by synthesizing Fe(III) chitosan nanoparticle n-benzaldehyde Schiff base (Fe(III)CnSb) and Fe(III) chitosan n-benzaldehyde Schiff base (Fe(III)CSb). The two materials were characterized by Fourier transform infrared spectroscopy (FTIR), X-ray diffractogram (XRD) and evaluated using the disc diffusion method against three gram-positive bacteria, two gram-negative bacteria and two fungi. The diffracted peaks of the Fe(III) chitosan nanoparticle n-benzaldehyde Schiff base showed peaks at 2θ=240 and 420 relative to the peak of Fe(III) chitosan n-benzaldehyde Schiff base of 2θ = 22.50 and 340. The difference in peak shift was attributed to the ionic bonding of Fe(III) complexation with the benzaldehyde mixture of the chitosan-Tpp backbone structure. Fe(III) chitosan nanoparticle n-benzaldehyde Schiff base has more antimicrobial activities than Fe(III) chitosan n-benzaldehyde Schiff base against the same bacteria and fungi tested
