Nanosensors offer a noninvasive, highly accurate alternative for glucose monitoring, transforming diabetes management.
By Arzoo PuriFeb 15 2024Reviewed by Megan Craig, M.Sc. Glucose monitoring is critical for managing chronic illnesses such as diabetes, which affects millions of people across the world. Traditionally, measuring glucose levels has proven invasive, requiring multiple blood samples and finger pricks. Here, we explore how nanosensors are revolutionizing glucose monitoring.
See our full range of equipment. Nanosensors vs. Traditional Monitoring Methods Conventional blood glucose monitoring involves fingertip pricking, in which individuals must try to keep their glucose levels within 4.4 and 6.7 mm/L. Nanosensors can provide precise glucose detection results. The glucose oxidase test is used by most glucose nanosensors to measure blood glucose electrically or chemically.
Notably, they reported that the fluorescence modulation of these nanosensors is governed by glucose binding to GOx rather than catalytic oxidation. These findings highlight the technology's great potential to revolutionize glucose monitoring in a variety of clinical and research settings.Detection of Glucose via pH or Charge Change Nanomaterial-based sensors, such as field effect transistors , can recognize glucose via pH or charge changes. These devices assess nanomaterial characteristics as influenced by charges near the sensor's surface or the solvent's pH.
The layer-by-layer construction of carbon nanotubes with GOx enables the monitoring of pH variations caused by glucose breakdown, as measured by conductance variations in the CNT layer. Furthermore, this patch may perform two functions: detecting glucose levels in sweat samples and enabling a precise supply of insulin for diabetes control via a touchable skin patch.
Over the last decade, artificial intelligence has emerged in an attempt to improve the efficacy of glucose sensors. The combination of nanosensors and artificial intelligence algorithms has tremendous potential for improving glucose data analysis and interpretation, allowing individualized treatment recommendations and predictive modeling to anticipate glucose variations and avert issues.
As nanosensor technology research and development progresses, the future holds enormous promise for discoveries that will enhance glucose monitoring and pave the path for customized healthcare.
