A team of researchers led by Dr. Michael McAlpine of Princeton University have developed a gold- and carbon-based biosensor that can be affixed to a tooth [1]. The purpose of the sensor, which is made up primarily of a very strong form of carbon called graphene, is to detect sequences of DNA that are specific to pathogenic bacteria.
Man’s best friend may someday turn out to be a physician’s tool for the detection of several types of cancer.
NBC Nightly News aired an intriguing story last night about dogs who have the ability to detect ovarian cancer [1]. The story referenced a new study published in the European Respiratory Journal that focused on canine scent detection for the diagnosis of lung cancer [2].
A study published earlier this year in the American Journal of Medical Genetics suggests that lymphoblast gene expression may be used to identify biomarkers for panic disorder. Researchers at the University of Iowa evaluated gene expression profiles in lymphoblasts (immature white blood cells) cultured from patients with and without panic disorder and found specific disorder- and sex-related differences [1]. A blood test for panic disorder and other mental health conditions based on the study results is being developed. However, a commercial diagnostic test may be premature as the study results are far from conclusive.
