  • Long-lasting hydrogel for targeting, imaging, and tumor metastasis without continuous auto-fluorescence

    Long-lasting hydrogel for targeting for imaging and tumor metastasis without autofluorescence, metastatic lesion often the main reason for the failure of cancer treatment. Tumor metastasis refers to tumor cells via lymphatic and blood vessels to reach other parts of the route from the primary site to continue the growth of metastases formation. Metastases generally small size, shape and diverse, randomly distributed in different organs, leading to cancer is difficult to cure. Therefore, the development of monitoring tumor metastasis A new method to study the metastatic behavior of tumor cells, is important for tumor therapy. Recently, the Institute of Chemical Engineering and Technology, Professor Yang Dayong research group designed and synthesized a long

  • Gospel diabetes: Nanjing University developed a gel patch microalgae treatment of chronic wounds

    Gospel diabetes: Nanjing University developed a microalgae gel patch treatment of chronic wounds, diabetes is one of the threats to human health and life safety of major diseases, and the prevalence of diabetes in the world has increased year by year. Currently, up to 25% of patients with diabetes due to poor blood circulation and wound complications and other chronic non-healing wounds, such as diabetic foot ulcers (DFU), severe cases can lead to amputation. Studies have shown that diabetes is delayed healing of chronic wounds caused by hypoxia impaired neovascularization results, therefore, reduced in the anoxic treatment of chronic wounds is urgent clinical treatment of diabetes

  • Macroscopic phase separation hydrogel microspheres

    Hydrogel microspheres macroscopic phase separation, the development of high mechanical strength, good flexibility and crack hydrogels have great academic and practical significance. Bis researchers typically by designing hydrogels, hydrogel slip ring, nanocomposite hydrogels, hydrogels topology and other ionically crosslinked hydrogels strategy to achieve high strength hydrogels. But the rational design of the next generation of hydrogels also affected by lack of research on the mechanism of strengthening. At present, the mechanism under strong hydrogel obtained is always derived from the microscopic and macroscopic properties of the network structure, i.e. the conformation affect the morphology and mechanical strength of the assembly is still at level assumptions. Therefore, the need to develop an effective technique
