PTT effects of Squarine dye based copolymer NPs on breast tumor burden on s mice. (a) Thermal imaging; (b) Thermal variations in tumor during PTT; (c) Tumor growth inhibition and (d) body weight analysis during treatment period; (e) Weight measures of tumor lesions post treatment with PBS, PBS + L, SQ1 NP, SQ1 NP + L. L refers NIR laser (915 nm, 0.5 W/cm2). Data present as mean ± SD, n = 5 (*** p < 0.01). (f) Histochemical analysis of tumor sections treated with PBS, PBS + L, SQ1 NP, SQ1 NP + L. The scale bar is 50 μm. (Reprinted permission American Chemical Society, 2020) [74].
