Modulatory Effect of Citrate Reduced Gold and Biosynthesized Silver Nanoparticles on α-Amylase Activity

Figure 5

Measurement of absorbance spectrum of α-amylase in presence of nanoparticles. Absorbance spectra of α-amylase at pH 7.4. Absorbance spectra were increasing with addition of (a) FR silver nanoparticles; (b) FB silver nanoparticles (5, 10, 20, 30, 40, and 50 μL), respectively; and (c) gold nanoparticles.
