We report on a competitive electrochemical detection system that is free of wash steps and enables the real-time monitoring of adenosine triphosphate (ATP) in a quantitative manner over a five-log concentration range. The system utilizes a recognition surface based on ATP aptamer (ATPA) capture probes prebound to electroactive flavin adenine dinucleotide(More)
A porphyrin that contains a single carboxylic acid group was synthesized and coupled to 2'-amino-2'-deoxyuridine. The resultant product contained a free 3' hydroxyl group and a 4,4'-dimethoxytrityl (DMT) protecting group on the 5' hydroxyl of the uridine, making it suitable for use in oligonucleotide synthesis. The 3' H-phosphonate derivative of this(More)
