DNA biosensor developed in the form of an urchin-like nanocluster

Nanotechnology for diagnostics – nanodiagnostics – is a growing area of research and development. In biological systems this type of nanotechnology could prove extremely useful in the detection of diseases. Biochemists and engineers from Missouri University of Science and Technology (Missouri S&T; MO, USA) have come together to develop a novel type of biosensor in the form of an ultrasensitive DNA biosensor. The DNA biosensor could enable the early diagnosis of cancer and genetic disorders by detecting DNA biomarkers of the diseases. A biological recognition element, a signal converter and a processor make up a standard electrochemical biosensor that can...
