Cells can produce unique electrical signals. These signals can be linked to various cancers, such as the breast, lung, liver, brain, pancreas and prostate cancers, meaning that they can be used as indicators for early cancer diagnosis. Thus, using electrical signals as indicators and targets for cancer treatments could potentially improve the outcome for cancer patients. A team of researchers from SUTD and A*STAR Bioinformatics Institute were developing a sensor for the detection of breast cancer cells as strong electrical signals can be found in these cells.
