Live/dead staining (ah) and viability (i) of 4T1-Luc cells before and after NIR laser irradiation for 10 min after the cells were cultured in medium containing BSA-coated AuNRs at different Au concentrations of 0.0, 0.2, 0.4 and 0.6 mM for 6 h. Green color indicates live cells while red color indicates dead cells. Data are presented as mean ± standard deviation, n = 3. No significant difference: N.S.; significant difference: * p < 0.05; *** p < 0.001.
