The development of a long-term wireless implantable biosensor based on fluorescence intensity measurement poses a number of technical challenges, ranging from biocompatibility to sensor stability over time. One of these challenges is the design of a power efficient and miniaturized electronics, enabling the biosensor to move from bench testing to long term validation, up to its final application in...
Fluorescent biosensors can be highly specific and sensitive, and may be engineered as implantable devices for metabolic monitoring. Commonly-used systems for glucose monitoring based on resonance energy transfer (RET) and competitive binding involve Concanavalin A (Con A), which is known to be toxic, and has problems of aggregation and irreversible binding. This work presents an improved RET assay...
