Treatment effect of mice with MCF-7 and MDA-MB-231 breast cancer cells. (A) Graph of nucleus-targeting ultrasmall CS-RuO2 NPs and for PTT under NIR-Ⅱ laser. (B) UV-vis-NIR absorption spectra of ultrasmall CS-RuO2 NPs at varying concentrations. (C) Temperature of tumor in live mice in two groups: 1) PBS + NIR-Ⅱ, 2) ultrasmall CS-RuO2 NPs + laser. (D) Representative digital photos of tumor under four groups treatment: 1) PBS, 2) PBS + laser, 3) ultrasmall CS-RuO2 NPs, 4) ultrasmall CS-RuO2 NPs + laser (reproduced from (Liu et al., 2020) with permission from Royal Society of Chemistry). (E) Schematic illustration of the preparation of NPPBTPBF-BT for PTT. (F) Absorption spectra of nanoparticle NPPBTPBF-BT and PBTPBF-BT in CHCl3. (G) Temperature change line during the three groups treatment. (H) The MDA-MB-231 tumor growth curves of different groups of mice (reproduced from (Cao et al., 2018) with permission from Elsevier BV). (I) HA-4-ATP-AuNFs-DOX for PTT. (J) UV–vis–NIR spectra of AuNFs with various HAuCl4 concentration. (K) The tumor volume changes of five groups’ treatment.
