Nanotube sensor detects Lyme disease

http://www.upenn.edu/pennnews/news/penn-researchers-attach-lyme-disease-antibodies-nanotubes-paving-way-diagnostic-device

A team led by Professor A. T. Charlie Johnson of the University of Pennsylvania has developed a biosensor from carbon-nanotube transistors that can rapidly detect the antigens of Lyme disease. The device can detect the biomarkers at concentrations as low as 1 ng/ml.

The group’s work is a continuation of similar strategies to detect prostate cancer biomarkers using CNTs. The researchers hope to one day be able to detect any disease with such nanotube devices simply by coating them with the appropriate proteins.
