LUO, N., D. W. HATCHETT, AND K. R. ROGERS. IMPACT OF POLYCYCLIC AROMATIC HYDROCARBONS OF THE ELECTROCHEMICAL RESPONSES OF A FERRICYNIDE PROBE AT TEMPLATE-MODIFIED SELF ASSEMBLED MONOLAYERS ON GOLD ELECTRODES. ELECTROANALYSIS. John Wiley & Sons, Ltd., Indianapolis, IN, 18(22):2180-2187, (2006).

Impact/Purpose:

The overall objective of this task is to develop scientifically sound sampling and bioanalytical approaches for screening and monitoring of hazardous wastes. These techniques are expected to provide the Agency with improved screening and field portable methods to characterize, reduce, and control risk to human health and the environment. Specific objectives will include development and characterization of the following concepts:

SPMDs for passive accumulation of TICs

Bioassays for toxic and genotoxic compounds

MIPs for volatile and semivolatile toxic organics

Rapid screening assays using the previously listed components.

Description:

The impact of pyrene on the electrochemical response of the ferricyanide probe using Self Assembled Monolayer (SAM)-modified gold electrodes was investigated using Cyclic Voltammetry (CV) and Square Wave Voltammetry (SWV). These results suggest the feasibility of using SAMs, particularly the crosslinked (3-mercaptopropyl) trimethoxysilane (MPTS)-SAMs, as a strategy for development of electrochemical sensing of molecularly imprinted SAMs.
