Figure 1From: Biomimetic Synthesis of Gelatin Polypeptide-Assisted Noble-Metal Nanoparticles and Their Interaction Studya TEM image of gelatin; b TEM image of AuNPs ( dark dots ) loaded by gelatin ( gray plates ) synthesized at 80°C ( C gelatin : 0.4%); c The magnified TEM images of b; d UV–vis of the Gelatin-AuNPs synthesized with 0.1, 0.15, 0.25, 0.5, 0.75, 1, and 2% gelatin solutions. The inset is the corresponding optical images of gelatin-AuNPs colloids (the gelatin concentration increasing from left to right).Back to article page
