The influence of the non-covalent interactions and chemical attachment of oligonucleotides (10 and 25 bases), composed of polyA, polyT, polyG and polyC, on the electronic structure of single wall carbon nanotubes (SWCNTs) is investigated by means of Raman spectroscopy. While interactions of SWCNTs with short length polyA, polyT and polyG increase with increasing incubation time, it decreases for longer polyA, polyT and polyG except for polyC, which interacts with SWCNT regardless of incubation time and base length.
