A multiplex electrochemical sensor platform for detection of blood-borne pathogens. (A) A portable, multichannel potentiostat with a chip mount for amperometric sensing. (B) A disposable, 16-sensor chip (2.5 by 7.5 cm) fabricated by gold deposition on a plastic substrate. Each electrochemical sensor consists of a central working electrode, a circumferential reference electrode, and a short auxiliary electrode. (C) A schematic representation of the sandwich binding scheme on the central working electrode with the self-assembly monolayer. The target is captured on the sensor surface by the capture probe (CP) and detected using the detector probe (DP) amperometrically. HRP, horseradish peroxidase; rRNA, ribosomal RNA.
