Scientists use nanosensors for first time to measure cancer biomarkers in blood

A team led by Yale University researchers has used nanosensors to measure cancer biomarkers in whole blood for the first time.
Nanosensors have been around for the past decade, but they only worked in controlled, laboratory settings," Reed said. "This is the first time we've been able to use them with whole blood, which is a complicated solution containing proteins and ions and other things that affect detection."
To overcome the challenge of whole blood detection, the researchers developed a novel device that acts as a filter, catching the biomarkers—in this case, antigens specific to prostate and breast cancer—on a chip while washing away the rest of the blood.
