A team led by Yale University researchers has used nanosensors to  
measure cancer biomarkers in whole blood for the first time. Their  
findings, which appeared December 13 in the advanced online  
publication of Nature Nanotechnology, could dramatically simplify the  
way physicians test for biomarkers of cancer and other diseases. The  
team, led by Yale's Dr. Mark Reed used nanowire sensors to detect and  
measure concentrations of two specific biomarkers: one for prostate  
cancer and the other for breast cancer.

During this week's podcast, Dr. Reed provides additional details on  
the research reported in the Nature Nanotechnology paper. He explains  
why the team employed a label-free biomarker detection technology and  
how his group was able to overcome the challenge of whole blood  
detection. Dr. Reed describes the advantages the new method has over  
other biomarker detection techniques and looks at the ways doctors  
might be able to use these novel nanosensor devices in daily medical  
practice.
