This finding is in agreement with that of Yang et al., who showed increased cancer cell death (~77.5%) using 50 μg/mL concentration of lactoferrin-functionalised AuNRs to target Hep G2 cancer cells and irradiated them using a 980 nm diode laser at a power density of 0.5 W/cm2 for 1 min [57]. The gene discussed is LTF; the disease is cancer.
