Evaluation of enzyme-based tear glucose electrochemical sensors over a wide range of blood glucose concentrations

Powering electronic contact lenses: current achievements, challenges, and perspectives

“…For a glucose sensing application, it would be important to mention several recent reports in the literature showing that the tear glucose concentration is quite adequately correlated (that is, real-time amounts) to blood glucose levels [5,26,27]. Given that the overall dynamic volume of basal tears is in the 10-ml range and that no known methodology can ensure that the entire volume is reliably and repeatedly exposed to the appropriate FC modules, glucose is an unlikely on-lens energy source, if conventional (bio) FCs are to be employed.…”

Sensing and Sensor Fundamentals

“…Biomedical applications include glucose measurements in blood samples (Wang, 2008) (Peng, et al, 2013).…”

A disposable biosensor for noninvasive diabetic diagnosis rest on the Au/TiO2 nano-composite intensified electrochemiluminescence

“…Even compare to the case of a continuous monitoring of glucose with an implantable device, the noninvasive ways are also better in avoiding antagonism from the immune system of human body which would deactivate the sensor after implantation, and to more efficaciously manipulate the insulin pump for in-vivo controlling of the glucose. Thus, some new researches have focused on the exploration of adaptive noninvasive devices for glucose detection in those succedaneous bodyfluid samples as urine [15], tear [16] or saliva [17]. Proportional to blood glucose [18], saliva is a more conveniently collected sample for noninvasive glucose detection for its rapid acquisition and painless operation.…”
