Massive efforts have been concentrated on the advance of eminent near-infrared(NIR) photothermal materials(PTMs) in the NIR-Ⅱ window(1000–1700 nm), especially organic PTMs because of their intrinsic biological safety compared with inorganic PTMs. However, so far, only a few NIR-Ⅱresponsive organic PTMs was explored, and their photothermal conversion efficiencies(PCEs) still remain relatively low. Herein, donor–acceptor conjugated diradical polymers with open-shell characteristics are explored for synergistically photothermal immunotherapy of metastatic tumors in the NIR-Ⅱ window. By employing side-chain regulation, the conjugated diradical polymer TTB-2 with obvious NIR-Ⅱ absorption was developed, and its nanoparticles realize a record-breaking PCE of 87.7% upon NIR-Ⅱ light illustration. In vitro and in vivo experiments demonstrate that TTB-2 nanoparticles show good tumor photoablation with navigation of photoacoustic imaging in the NIR-Ⅱ window, without any side-effect. Moreover, by combining with PD-1 antibody,the pulmonary metastasis of breast cancer is high-effectively prevented by the efficient photo-immunity effect. Thus, this study explores superior PTMs for cancer metastasis theranostics in the NIR-Ⅱ window, offering a new horizon in developing radical-characteristic NIR-Ⅱ photothermal materials.

This study aimed to investigate the effects of different proportions of dietary fermented sweet potato residue(FSPR) supplementation as a substitute for corn on the nutrient digestibility, meat quality, and intestinal microbes of yellow-feathered broilers. Experiment 1(force-feeding) evaluated the nutrient composition and digestibility of mixtures with different proportions of sweet potato residue(70%, 80%,90%, and 100%) before and after fermentation. In Experiment 2(metabolic growth), a total of 420 oneday-old yellow-feathered broilers were randomly allocated to 4 groups and fed corn-soybean mealbased diets with 0, 5%, 8%, and 10% FSPR as a substitute for corn. The force-feeding and metabolic growth experiments were performed for 9 and 70 d, respectively. The treatment of 70% sweet potato residue(after fermentation) had the highest levels of crude protein, ether extract, and crude fiber and improved the digestibility of crude protein and amino acids(P < 0.05). Although dietary FSPR supplementation at different levels had no significant effect on growth performance and intestinal morphology, it improved slaughter rate, half-chamber rate, full clearance rate, and meat color, as well as reduced cooking loss in the breast and thigh muscles(P < 0.05). Dietary supplementation with 8% and 10% FSPR increased the serum immunoglobulin M and immunoglobulin G levels in broilers(P < 0.05). Furthermore, 10% FSPR increased the Shannon index and Ruminococcaceae＿UCG-014, Ruminococcaceae＿UCG-010 and Romboutsia abundances and decreased Sutterella and Megamonas abundances(P < 0.05). Spearman's correlation analysis showed that meat color was positively correlated with Ruminococcaceae＿UCG-014(P < 0.05) and negatively correlated with Megamonas(P < 0.05). Collectively, 70% sweet potato residue(after fermentation) had the best nutritional value and nutrient digestibility. Dietary supplementation with 8% to 10%FSPR as a substitute for corn can improve the slaughter performance, meat quality
