Electrochemiluminescent Arrays For Toxicity Screening.

The Electrochemical Society Interface • Summer 2009 Electrochemical applications to biomedical problems began in the early days of quantitative polarography and this topic was reviewed in a classic book by Březina and Zuman published over 50 years ago.1 In recent years, commercial electrochemical enzyme sensors have become the method of choice for diabetic patients to measure glucose in their blood,2 and a myriad of electrochemical sensors have been developed to detect other biomolecules including DNA for genetic analysis and protein biomarkers for disease detection and monitoring. Advantages such as low cost and mobility of instrumentation, and simplicity of procedures promise to lead to eventual medical point-of-care applications.
