  • Non-invasive nanotube device detects disease with one drop of blood

    http://www.njit.edu/news/2013/2013-218.php Professors Reginald Farrow and Alokik Kanwal of the New Jersey Institute of Technology have created a carbon nanotube-based device to non-invasively and quickly detect mobile single cells with the potential to maintain a high degree of spatial resolution.  They are now overseeing the manufacture of a prototype lab-on-a-chip that would enable a physician to detect…

  • Nanotube sensor detects skin cancer

    http://www.monell.org/news/news_releases/monell_led_research_identifies_scent_of_melanoma A study from the Monell Center and the University of Pennsylvania suggests that non-invasive odor analysis may be a valuable technique in the detection and early diagnosis of human melanoma.  The researchers used sophisticated sampling and analytical techniques to identify VOCs from melanoma cells at three stages of the disease, as well as from normal…

  • 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…

  • Non-invasive diabetes monitoring through breath analysis

    http://www.news.pitt.edu/news/diabetes-breathalyzer University of Pittsburgh professor Alexander Star, Dan Sorescu of the National Energy Technology Laboratory, and graduate student Mengning Ding have demonstrated sensor technology that could simplify the diagnosis and monitoring of diabetes through breath analysis alone. The researchers used a “sol-gel approach,” a method for using small molecules (often on a nanoscale level) to produce solid materials.…

  • Nanotube sensor detects glucose in saliva

    http://www.technologyreview.com/view/514456/carbon-nanotube-sensor-detects-glucose-in-saliva/ A team led by Mitchell Lerner at the University of Pennsylvania has developed a carbon nanotube based transistor that can detect glucose levels in body fluids, including saliva. The nanotubes are coated with molecules of pyrene-1-boronic acid, which makes them highly sensitive for glucose detection. When exposed to glucose, the nanotube transistor’s current-voltage curve changes,…
