Aaron Wheeler holds a petri dish bearing a lump of breast tissue that resembles, in size and appearance, a piece of chewed gum.
In his right, the University of Toronto chemist holds a microchip array, about the size of a credit card, bearing a drop of red liquid about a thousand times smaller than the glob of flesh. The drop represents the minute amount of cells that Wheeler’s tiny board needs to accurately gauge estrogen levels in a woman’s breast tissue. Read more

Clinical researchers at Princess Margaret Hospital (PMH) can now answer the question that baffles many clinicians – why do some men with elevated prostate specific antigen (PSA) levels who are carefully monitored and undergo repeated negative biopsies still develop aggressive prostate cancer?

Microfluidics chips allow scientists to study circulating cancer cells and determine their vulnerabilities.
By Emily Singer from MIT Technology Review
In a new clinical trial for prostate cancer, scientists will capture rare tumor cells circulating in patients’ blood, analyze them using a specialized microchip, and use the results to try to predict how well the patient will respond to a drug. The trial reflects a new phase of personalized medicine for cancer, enabled by microfluidics technologies that can isolate scarce cancer cells and detect very small changes in gene expression.
