The main advantage of this new type of electrode is its full compatibility with media containing a high amount of organic solvent (methanol, acetonitrile) %K Glassy carbon paste electrode %K linear scan voltammetry %K differential pulse voltammetry %K voltammetry with adsorptive accumulation %K 1-nitropyrene %K 1-aminopyrene. %U http://www.mdpi.com/1424-8220/4/5/47
