Investigating the Antimicrobial Activity of Vancomycin-Loaded Soy Protein Nanoparticles

Figure 2

FTIR spectra of designed nanostructures. (a) Vancomycin, (b) soy protein nanoparticle (SPNs), and (c) vancomycin-loaded soy protein nanoparticle (vancomycin-SPNs). Characteristic changes in intensity and displacement of the index peaks in the vancomycin-SPNs compared to the free drug and the drug-free SPNs.
