Biosensing SWCNTs have nanoscale dimensions that fit to the size of biological species. Due to this size compatibility and their large surface-to-volume ratio, they are sensitive to changes in their chemical environment. Through covalent and non-covalent surface functionalization, SWCNTs can be precisely tailored for selective molecular interactions with a target analyte. The SWCNT represents the transduction unit that converts the interaction into a signal change (optical or electrical). Due to continuous progress in the development of detection strategies, there are numerous examples of the use of SWCNTs as highly sensitive nanosensors (even down to the single molecule level) for a variety of important biomolecules. Examples include the detection of reactive oxygen and nitrogen species, neurotransmitters, other small molecules, lipids, proteins, sugars, DNA/RNA, enzymes as well as bacteria.
