LALBA and breast carcinoma: Yang et al. have synthesized alpha-lactalbumin stabilized AuNCs with three different emission wavelengths of 450 nm, 520 nm, and 705 nm (Figure 3a), and demonstrated good in vivo fluorescence imaging of MDA-MB-231 human breast cancer using the 705 nm AuNCs (Figure 3b), and a possibility for utilizing the AuNCs for fluorescence-guided surgical resection (Figure 3c) [69].
