A nanohybrid adduct of the widely used, functional dye, daunomycin (DM), with single-walled carbon nanotubes (SWNTs) was prepared. Ultraviolet-visible-near infrared and fluorescence spectroscopy and electrochemistry of DM-functionalized SWNTs reveal that DM interacts with SWNTs through strong π–π stacking and there is a significant photo-induced charge-transfer interaction between the two components...
A novel electrochemical sandwich-type gene sensing system was designed by using a DNA probe (DNA-probe1) immobilized on a gold electrode, the target DNA, and another DNA probe (DNA-probe2) conjugated on a single-walled carbon nanotubes/ferrocene (Fc–SWNT) adduct. In this sandwich-type gene-sensing electrode, the Fc–SWNT adduct could significantly amplify the electrochemical response of the reduction...
