Photothermal Therapy

The Importance of Photothermal Therapy


Traditional tumor treatment methods such as chemotherapy have certain limitations, so the treatment effect is often not ideal. As a new type of treatment method, nano-material-based tumor photothermal therapy technology has gradually attracted widespread attention for its minimally invasive, high-efficiency, low side effects and ability to inhibit tumor metastasis. Tumor photothermal therapy is generally used in conjunction with chemotherapy, radiotherapy and immunotherapy.

Accelerate Research and Practice of Graphene in Photothermal Therapy

Graphene nanoparticles have strong absorption capacity for lasers in the ultraviolet to near-infrared region, and have a strong photothermal effect. Therefore, they have also attracted the attention of many researchers in the field of tumor photothermal therapy. Studies have found that the absorption capacity of nano-sized reduced graphene oxide for near-infrared light is 6 times higher than that of unreduced graphene, which can achieve a smaller dose of photothermal treatment. Researchers can also achieve the multifunctional application or collaborative treatment of graphene nanoparticles for tumor diagnosis and treatment by surface modification of graphene and other means.
