Patent ID: 8716029

Claim:
A device for selective detection of a target molecule, the device comprising: a plurality of single-wall carbon nanotubes having a first level of conductivity; and a peptide sequence distributed on an outer surface of the single-wall carbon nanotubes, the peptide sequence further comprising a first peptide domain that is capable of binding to at least a portion of the outer surface of the single-wall carbon nanotubes and a second peptide domain that is capable of selectively binding to the target molecule, wherein the single-wall carbon nanotubes have a second level of conductivity after binding of the target molecule to the second peptide domain wherein the first peptide domain comprises SEQ ID No.1 and the second peptide domain comprises SEQ ID No.2, wherein the second peptide domain is coupled to the first peptide domain by a sequence comprising SEQ ID NO.4.
