Finding a few foes among billions of cellular friends
Date:2/26/2014

rgeting aptamers were detected by cyclic voltammetry of thionine. The system had a wide linear response range and a detection limit down to just a few cells.

There's still a long way to go to get a device into the clinic, but Wang can see the potential of the sturdy inorganic nanoprobes.

"We can actually quantify the biomarkers expressed on cancer cells, and because the expression levels on the cancer cells are quite different from the normal cells, we can actually identify the cancer cells," he says. "Since the sensitivity is really high, if you have low-abundance cancer cells in the body, we should be able to detect them."
