(A) UV-vis absorbance spectra for citrate-coated AgNPs incubated in digestive juices without proteins. (B) UV-vis absorbance spectra for PVP-coated AgNPs incubated in digestive juices without proteins. (C) UV-vis absorbance spectra for citrate-coated AgNPs incubated in digestive juices with proteins (D) UV-vis absorbance spectra for PVP-coated AgNPs incubated in digestive juices with proteins. One representative determination of two is shown. S, saliva; G, gastric juice; I intestinal juice.
