HSP70 expression in 4T1 cells pretreated with free TPL: A) and TPL-GNR@MSN-3P; B) under heat or not by western blotting analysis, β-actin was used as an internal control. C) Fluorescence images of live (green) and dead (red) 4T1 cells co-stained with Calcein-AM and EthD-1 after different formations treatment with or without 808 nm laser (2 W/cm2, 5 min). D) Normalized cell viability of 4T1 cells treated with free TPL, GNR@MSN-3P and TPL-GNR@MSN-3P under 808 nm laser irradiation or not (2 W/cm2, 5 min).
