Figure 5

Alteration in the UV–vis spectrum and appearance of AuNPs by mixing with PBS and proteins. Alteration in the original UV–vis absorption spectrum and appearance of tannic acid-stabilized AuNPs (a: 30-nm, 127 μM) after mixing with phosphate buffered saline (PBS, pH 7.4, 100 mM) and 0.15 mg/mL protein (BSA or HLM) under different adding order of agents. Inset shows the flow chart of this procedure and digital photos of AuNPs solution in every step.
