New probe shows promise for gastric cancer

The nanoprobe emits yellow-green fluorescence for imaging under blue laser light, and is able to target human gastric cancer tissue. It is the first probe to be designed for the diagnosis of early gastric cancer in this way, which is of great clinical significance, said Yang Shiming, director of the team from the hospital's gastroenterology department.

He said the probe was jointly devised and built by the hospital, the National Center for Nanoscience and Technology, along with experts worldwide.
