Surface-grafted polypeptides have drawn considerable attention in recent years because of their distinct ordered secondary structures. The ordered structures offer unique thin film properties. For example, the grafted poly(γ-benzyl L-glutamate), poly(N-carbobenzyloxy-L-lysine) thin films on solid substrates demonstrated high electro optical and piezoelectric efficiency, as a result of the presence of net dipole moment in the films. The grafted poly(L-glutamic acid), poly(L-lysine) on membranes was employed as a pH-sensitive gating for water permeability because its conformational transition between helix and coil can be modulated by pH. In this study, we attempt to synthesize surface-grafted polypeptide films on Fe2O3 nanoparticles surface. To verify the synthetic results, both DLS and Fourier transform infrared spectroscopy (FTIR) will be used to characterize the film thicknesses, refractive indices, chemical compositions, and secondary structures. |
