Description
Ramazan Bayat and colleagues built a near-infrared sensor for dopamine in a 2026 nanotechnology study, using single-walled carbon nanotubes wrapped in a repeating short DNA strand. Dopamine is a key brain messenger, and detecting it selectively among other body chemicals is a standing challenge.
The wrapped nanotubes glow in the near infrared. Their brightness rose as dopamine levels increased across the tested range of 10 to 100 µM, while other biological samples gave no matching response. The detection limit worked out to 4.2 × 10−5 M, with a quantification limit of 13.24 × 10−5 M. Because nanotube glow does not fade or blink like ordinary dyes, the authors see the sensor as a candidate for longer-term dopamine monitoring tasks.
