Direct detection of circulating tumor cells in blood samples

Tumor cells circulating in blood are markers for the early detection and prognosis of cancer. However, detection of these cells is challenging because of their scarcity. Scientists have now introduced an ultrasensitive method for the direct detection of circulating tumor cells in blood samples. It is based on the amplified, time-resolved fluorescence measurement of luminescent lanthanide ions released from nanoparticles that bind specifically to tumor cells.
