Chinese and American researchers have developed tiny elastic balls that can be used for cancer diagnosis

researchers in China and the United States have developed a tiny elastic ball similar in size to a cell that measures compression stress between cells, a technique that could be used in early diagnosis of cancer.
Researchers at Central China University of Science and Technology and the University of Illinois at Urbana-Champein used microflow-controlled chips and elastic alginate polymers to create tiny elastic balls with similar diameter, force and chemical properties to cells, according to a study published on
on April 14.
Wang Ning of Huahua University of Science and Technology added fluorescent nanoparticles to the elastic ball to quantitatively analyze the deformation of the elastic ball. Experiments show that these tiny elastic balls compatible with organisms can measure the "biological force" at a three-dimensional scale when adhered to living cells.
Wang Ning told Xinhua that "biological force" is a force produced by living cells "type II myoglobulin", which belongs to an electromagnetic force and plays an important role in cell growth, development and differentiation.
said that the use of "biological force" measurement of new technologies can regulate the physiological microencienties, to achieve early diagnosis, treatment and cure of certain complex diseases.
team used elastic ball technology to find that malignant tumor regenerative cells and normal stem cells produce different "biological forces." Measuring the "biological forces" between cells could be a tool for early cancer diagnosis and help explain how synthetic drugs that stop cancer metastasis work, Wang said. (Source: Xinhua Zhouzhou)
