Near infrared fluorescent carbon nanotubes for biological detection use

That single-walled carbon nanotubes near-infrared fluorescence combined with microfluidic chip is used for rapid detection of mercury ion of high sensitivity.

Molecular detection using near infrared light between 0.9 and 1.3 eV has important biomedical applications because of greater tissue penetration and reduced auto-fluorescent background in thick tissue or whole-blood media. Carbon nanotubes have a tunable near infrared emission that responds to changes in the local dielectric function but remains stable to permanent photobleaching.

We use the nonconjugate dispersed method,  fluorescence reaction is observed in 800-1600 nm near infrared region.
