Chinese and American scholars have developed new materials to carry chemotherapy drugs

Xinhua News Agency, Nanjing, December 2 (Reporter Wang Wei) reporter 2 from the
Suzhou Medical Institute was informed that china and the United States research and development personnel have recently prepared a new type of nanomaterials that can carry chemotherapy drugs. This gives new hope for efficient and low-toxic tumor treatment.
nanomaterial is like a dutiable 'nano porter' in a living organism, " he says. They accurately bring chemotherapy drugs to the tumor and then give them exactly as needed for treatment. Dong Wenfei, a researcher at Suzhou Medical Institute who led the study, said.
, the main components of the new material are selenium and silicon dioxide, which can be reduced by X-ray exposure. Animal experiments show that using bionic strategies to wrap tumor cell membranes around the surface of the material can play an effective role in accurately guiding chemotherapy drugs to the patient.
at the same time, low-dose X-ray exposure can accurately control the release process of the drug. Comparative monitoring in breast cancer mice showed that after using the new material to carry chemotherapy drugs, the effect of tumor treatment was more than doubled compared to conventional chemotherapy, and the toxic side effects were significantly reduced.
also found that chemotherapy drugs powered with new materials stimulate the body to produce tumor-specific immune responses, " he said. This means that in the future it is not only expected to be used to treat primary tumors, but may also effectively inhibit tumor metastasis. Study participant and researcher at South China University of Technology, Yan Dan, said.
the study was
with Suzhou Medical Institute, South China University of Technology, Columbia University, etc. The results were recently published in the international journal Advanced Materials.
