(a) Fluorescence titration of 100 nM FITC-β-gal with NP_Pep in 5 mM phosphate buffer (without and with NaCl of 150 mM) at 25 °C. (b) The CD spectra of the protein (100 nM) before and after addition of nanoparticles in 5 mM phosphate buffer at 25 °C. In the inset, the percent of secondary structures calculated using DICHROWEB indicating minimal conformational change upon nanoparticle addition.
