Chinese researchers develop nanomaterial inhibiting tumor growth by over 80%

Researchers from Xi'an Jiaotong University in northwest China's Shaanxi Province announced recently that they have developed a nanomaterial which can achieve a tumor inhibition rate of more than 80 percent.

The improvement of tumor inhibition rate is expected to better treat cancer and other related diseases.

Scientific studies suggest that active oxygen species is able to kill cancer cells quickly.

The latest nanomaterial developed by the researchers including Dang Dongfeng, professor of the university's Department of Chemistry, may realize independent regulation in living organisms according to needs and improve the production efficiency of active oxygen species.

"Our nanomaterial can be regulated on demand. As a result, it can get (active oxygen species) well concentrated and retained at the tumor site. Through the tail vein injection, the nanomaterial can be quickly targeted to the lesion of tumor. With the use of external light sources, the generation of active oxygen can be achieved," said Dang.

How to design and produce nanomaterial of appropriate sizes and extend their residence time in the tumor microenvironment are major challenges in the current field of optical materials research.

This achievement can realize the self-assembly of nanomaterial, which is expected to improve the targeting and retention effect.

"Our nanomaterial has a very good driving force for assemblies. It can well realize assemblies even in a living organism to ensure that it can stay well in tumor cells, intelligently select tumor cells and cancer cells, and avoid killing normal cells and tissues. In this way, a very good therapeutic effect is expected to be achieved," he said.

At present, the nanomaterial has been developed in the laboratory and verified at the cellular and biological levels, with the tumor inhibition rate reaching more than 80 percent.

"Currently, we are conducting in-depth cooperation and negotiations with relevant hospitals, hoping to proceed with application and research on early-stage clinical transformation, realize the clinical application of some optical diagnosis and treatment, and provide a very good choice and idea for the treatment of some cancers," said Dang.
