(A) Fluorescence confocal images of HepG2 cells after incubation with AuNCs@ew–Hg(II) for 0, 12, 15, 21, 30 and 45 min. (B) Fluorescence confocal images of normal cells (HT22 cells) after incubation with AuNCs@ew–Hg(II) for 1.0 h. The images in the left column show the fluorescence of the AuNCs@ew added to HT22 cells; the middle column shows the DIC images of cells in bright field; and the right column shows the merging of the two previous images.¹³⁹ “Reprinted from Sensors and Actuators B: Chemical, 240, Lu Tian, Wenjing Zhao, Lin Li, Yaoli Tong, Guanlin Peng, Yingqi Li, Multi-talented applications for cell imaging, tumor cells recognition, patterning, staining and temperature sensing by using egg white-encapsulated gold nanoclusters, 114-124, Copyright (2017), with permission from Elsevier.”
