Abstract:
1. A system for measuring an analyte of interest dissolved in a fluid media, comprising: (a) an insertion tube having a distal portion and a proximal portion, wherein the insertion tube comprises an implantable cardiac stimulation device housing the sensor in communication with a tissue surface; (b) a nanoelectronic sensor mounted adjacent the distal portion of the tube, the insertion tube configured to place the sensor adjacent at least one mucosal surface of the patient upon insertion of the distal portion into at least one body cavity or lumen of the patient, so as to permit diffusion of the analyte of interest through the mucosal surface to the sensor; the sensor including: (c) a hydrophobic filter element mounted adjacent the insertion tube and arranged to lie between the nanoelectronic sensor and the at least one mucosal surface; and (d) a measurement instrument in communication with the sensor and configured to receive at least a signal from the sensor indicative of a response of the sensor to at least the analyte of interest.
