• of appearance for [AgO2CCH2OMe(PPh3)]. Methods of Investigation Experimental The synthetic methodologies were performed under an atmosphere of argon with the solvents degassed prior to use. Ethanol (99%) was distilled from sodium/diethyl phthalate, and acetonitrile (99%) by distillation from sodium

• binding capacity of the sensor surface. As a simple and environmentally highly relevant model, binding of the plasticizer diethyl phthalate (DEP) via π-stacking was monitored on the rGO gold nanohole array realizing a limit of detection of as low as 20 nM. The concentration-dependent signal change was

• with analytically relevant amounts of DEP during which significant changes in the SPR signal are observed. It is expected that this concept can be successfully transferred to enhance the sensitivity in SPR sensors. Keywords: diethyl phthalate; environmental sensing; nanohole array; nanosphere

• referred to as plasmon–graphene hybrids [37]. On the other hand, interactions of molecules with aromatic systems via π-stacking is strongly promoted by the sp2-hybridized carbon atoms arranged in a honeycomb structure. In this study a sensor for diethyl phthalate as model analyte was developed. It is known
