Fig. 6
SEM characterization of (i) Silica Nanoparticles (SiNP), (ii) glutaraldehyde coated SiNP (SiNP-Glu) and (iii) peptide/epitope imprinted SiNP (MIP). Similarly, (iv) and (v) represent FTIR characterization after each coating step. Due to the formation of a thin polymer layer formed, the comparative differences in the spectra are less. Also, MIPs were rebound with the peptide and characterized (MIP + peptide) (vi). Slight differences in spectra and appearance of a new peak at 880 cm−1 indicate the peptide bound to the MIPs. NIP represents non-imprinted SiNP.
