Crystal Growth and Kinetic Behaviour of Pseudoalteromonas espejiana Assisted Biosynthesized Gold Nanoparticles

Figure 5

TEM images of AuNPs growth behaviour at varying time intervals: 0-2 h (a), 2-12 h (b), 12-24 (c), and 24-48 h (d) are depicted. The AuNPs size showed an increment at successive time interval due to fusion of smaller nuclei leading at a bigger particle due to crystal growth. All AuNPs in the images were synthesized with HAuCl₄ as a precursor ion. In the images, the scale on the bottom left corner represents 100 nm.
