High sensitivity carbon nanotube based electrochemiluminescence sensor array

► Ink jet printed highly sensitive vertically aligned SWCNT forest-ITO ECL sensor array. ► Silicate nanoparticles decorated with an ECL generating metal complex produce a significantly brighter emission. ► Wide linear dynamic range for IgG (20 pM to 300 nM) with detection limit as low as 1.1 ± 0.1 pM.
