Nano-chip to separate and analyze protein biomarkers in blood samples

Authors

Researchers from Tel Aviv University in Israel have developed a nanowire-based device to separate and analyze protein biomarkers in blood samples. As they report in Nano Letters, the filtering, separation, and analysis all occurs on a single chip — and rapidly. The chip, adds ScienceNews, is made of two compartments, one that is full of a “forest” of densely packed nanowires coated with protein-specific antibodies and one that contains flat nanowires, also coated with antibodies, that are connected to electrodes. The researchers tested their device on its ability to detect troponin T, which it was able to do sensitively and in less than 10 minutes. “It’s clever,” Yale University’s Tarek Fahmy tells ScienceNews. “They are doing separation and concentration on the same chip.”
