“…observed a decrease in Cys thiyl radical when ionic strength was increased. 84 The authors rationalized this observation by invoking counter ion clusters which surround charged molecules in solution, thereby retarding their interaction and ability to generate radicals. This diffusion limiting explanation is only partially satisfying for the bridged viologens since the response of the probe in solution without aminothiols (designated as 'blank') also decreased.…”

Increased blood plasma concentrations of the aminothiol homocysteine (Hcy) are associated with a variety of disease states including those which cause impaired renal function, many forms of cardiovascular disease, and neurodegenerative diseases such as Alzheimer's. Therefore, Hcy has the potential to be a significant diagnostic biomarker.Routine monitoring of Hcy plasma concentration is encumbered by the time and resources required to quantify Hcy using currently accepted instrumental analysis methods. As part of the continuing effort to develop a quick, reliable, inexpensive, and user-friendly test to quantify Hcy at the point of care, we have designed a series of novel iii Acknowledgements
