摘要：
The present invention is broadly concerned with the crafting and manufacturability of an implantable enzymatic-based sensor characterized by a small size, optimum geometry, linearity of response over the concentration range of interest, extended shelf-life, selectivity for the analyte in question, and the ability to exclude bioactive interferents. More particularly, it is preferably concerned with a general approach to optimize the performance of the biorecognition elements required to produce biosensors of the type designed to provide, and in conjunction with a suitable signal processing unit, a current which is proportional to the concentration of the analyte of interest. The biosensors described herein may be implanted in vivo, including intra-cerebral, sub-cutaneous, intra-muscular, inter-peritoneal oral, serum, and vascular implantation, the majority of which may act as a surrogate for systemic monitoring and used to monitor analytes of interest in real-time. Multiple biosensors can be joined together to allow for the simultaneous recording of multiple analytes of interest. In addition to the in vivo applications, sensors of the design described herein may also find use in medical monitoring, industrial processes, fermentation, environmental monitoring, and waste water stream monitoring. The present invention offers co-factor enhancement of the biorecognition element, providing access to a range of biorecognition elements heretofore difficult to incorporate into a manufacturing process for the large-scale production of biosensors.
