In vivo magnetic resonance imaging (MRI) scans and tumoral heat shock protein HSP70 expression. (A) Tumor-bearing BALB/c mice were intratumorally injected with saline or NaYF4:Yb,Er@PE3@Fe3O4 nanoprobes, followed by either near-infrared irradiation (NIR) irradiation or not. Five days later, both T1- and T2-weighted MRI scans were captured from each treatment group. (B) Immunohistochemical analysis of tumoral HSP70 expression in control mice and those receiving photothermal therapy. This experiment was repeated three times.
