Description General description 3,3′-Diethylthiacarbocyanine iodide (DTCI) is a cyanine dye, which acts as a donor in the electrochemical system. It can be used in the development of electrochemical cells. Application DTCI may be incorporated as a layer on gold nanorods, which can be used in surface enhanced resonance Raman spectroscopy (SERRS). It may be coated on a fused silica wafer, which can potentially be used in the development of solid state dye doped polymeric laser. Packaging 1 g in glass bottle 250 mg in glass insert
