Diagnostic test distinguishes cancer cells based on acidity levels June 1

Cancerous cells have a higher pH than healthy cells—an observation researchers at the National University of Singapore have used to create a diagnostic test.  “The test works like this: First, a pH-sensitive dye called bromothymol blue is applied onto patients’ cells maintained in cell culture dishes. Contact with the dye triggers a color change in cells, which varies depending on their acidity levels. Next, microscopes capture images of the cells. A machine-learning algorithm then analyzes the images and generates a report.”  MORE
