June 15, 2013 – 12:03 am
  • Odors from human skin cells can be used to identify melanoma - According to new research from the Monell Center and collaborating institutions, odors from human skin cells can be used to identify melanoma, the deadliest form of skin cancer. In addition to detecting a unique odor signature associated with melanoma cells, the researchers also demonstrated that a nanotechnology-based sensor could reliably differentiate melanoma cells from normal skin cells.(10.1016/j.jchromb.2013.05.007)

    Luminous bacterial proteins detect chemicals in water

    June 14, 2013 – 7:03 am
  • Luminous bacterial proteins detect chemicals in water - Scientists have developed a simple color sensor principle which facilitates the detection of residual medications, trace metals from industrial process waters, and many other substances. This is the concept: If the analyzed sample shines red, then the water is 'clean;' if its color turns green, however, then it contains the substances the scientists wish to detect.(10.1016/j.snb.2013.05.051)
