Selective coatings create biological sensors from carbon nanotubes
December 13, 2004 | Source: Medical News Today
University of Illinois at Urbana-Champaign researchers have developed protein-encapsulated single-walled carbon nanotubes that alter their fluorescence in the presence of specific biomolecules.
The technique could generate many new types of implantable biological sensors. The researchers have already built a near-infrared nanoscale sensor that detects glucose.
