2/15/2024 0 Comments Cancer tissue engineering scaffoldPTAs are the critical factor in PTT, and the choice and use of the PTAs is important for the success of PTT. It uses the photo-heat conversion of photothermal agents (PTAs) to produce a hyperthermic effect to destroy cancer cells, and has the advantage of less severe side effects. Photothermal therapy (PTT) is an effective treatment that has been widely considered in recent years. Surgery cannot remove all tumor cells from the primary lesion area and may cause tissue defects that are difficult to self-heal. Chemotherapy and radiation therapy involve high doses of anticancer drugs and radiation, which lead to side effects and serious effects on the overall health of patients. However, these treatments have some associated problems. Traditional treatments of cancers include surgical resection, chemotherapy, and radiation therapy. This review summarizes these latest advances and discusses the future prospects.Ĭurrently, cancer is a major health problem due to its high morbidity and mortality. The synergistic effects make the composite scaffolds attractive for biomedical applications. A variety of composite scaffolds of photothermal nanomaterials have been prepared to combine the advantages of different modalities to maximize their therapeutic efficacy with minimal side effects. Meanwhile, the composite scaffolds can stimulate the reconstruction and regeneration of the functional tissues and organs after ablation of cancer cells. In recent years, PTAs and three-dimensional scaffolds have been hybridized to realize the local delivery of PTAs for the repeated ablation of cancer cells. The PTAs are systematically or locally administered and become enriched in cancer cells to increase ablation efficiency. PTT relies on the photoconversion capacity of photothermal agents (PTAs), and a wide variety of nanomaterials have been employed as PTAs for cancer therapy due to their excellent photothermal properties. Photothermal therapy (PTT) has attracted broad attention as a promising method for cancer therapy with less severe side effects than conventional radiation therapy, chemotherapy and surgical resection.
