Carbon nanotubes (CNTs) absorb and fluoresce in the IR region of the EM spectrum to which the human body is transparent. Because of this and other unique properties, CNTs are being heavily investigated for medical imaging, biochemical sensors, and targeted drug delivery applications.
Nanotube fluorescence spectra (785 nm excitation) showing unreacted spectrum (blue line), spectrum after addition of 1 mumol of AB to 1 ml 10 mg l-1 SWNTs suspended in 1% SDS/D2O (black line), and recovered spectrum after addition of excess NADH (red line).
