dsDNA-Encased Single-Walled Carbon Nanotubes

dsDNA-Encased Single-Walled Carbon Nanotubes serve as near infrared optical probes. With or without additional regents, it can be used for measuring a variety of species such as reactive oxygen species, glucose, alcohol, neurotransmitters (dopamine, serotonin, norepinephrine, and epinephrine), nitrate and nitrite, antioxidants, etc.
