E. Coli, Sensor Developed
Submitted by nestorb on Thu, 2007-06-14 13:47. The sensor features a vibrating cantilever, supported at one end and coated with antibodies. The antibodies are specific to the desired target such as E. coli, anthrax or proteins that are biomarkers for diseases such as prostate cancer. When the target is present in a sample flowing past the sensor, it binds to the cantilever and changes the frequency of vibration so it can be read electronically.

FDA clears Cepheid's MEMS-based rapid test for meningitis
Submitted by nestorb on Tue, 2007-03-20 23:54. Bacterial meningitis can be deadly within two days. "Because this test is significantly faster than existing methods for diagnosing meningitis, it could minimize delays in treating patients. Swift recognition of the cause and appropriate treatment is critical to patient recovery,"
DNA test detects low-level uranium
Submitted by nestorb on Thu, 2007-03-01 21:50. DNA sensor can detect traces of uranium contamination nearly 3,000 times lower than the level considered hazardous to human health. The technology eventually might be contained in a fast and easily portable on-site testing system for uranium.
